Add call to ieee80211_networks_free() to avoid potential memory
leak if allocation of pHTInfo fails.

If the third allocation fails only the first successful allocation
is freed, not the second.

The function HTSetConnectBwModeCallback() is only used in the file
in which it is defined, so has been changed to being of type 'static'.

Additionally the function is defined after it is used so a prototype
was included in the file. This prototype, in the middle of the file
has been removed and the function implementation moved so that it is
defined before it is used in the file.

This is a coding style change which should have no impact on runtime
code execution.

Remove the redundant declaration of the function HTSetConnectBwMode()
as it is not needed in the code. The function is already declared
in header file, multiple declarations add nothing.

This is a style change which should have no impact on runtime code
execution.

The function HTMcsToDataRate() is not used outside the file in which

removed from the header file.

The function HTHalfMcsToDataRate() is unused in code so has simply
been removed from the code.

As a result two static functions, (IsHTHalfNmode40Bandwidth and
IsHTHalfNmodeSGI), are not longer called, so they have been removed
as well.

These are coding style changes which should have no impact on
runtime code execution.

Clang generates a warning when it sees a logical not followed by a
conditional operator like ==, >, or < because it thinks that the logical
not should be applied to the whole statement:

drivers/staging/rtl8188eu/core/rtw_ieee80211.c:293:8: warning: logical
not is only applied to the left hand side of this comparison
[-Wlogical-not-parentheses]

It assumes the author might have made a mistake in their logic:

if (!a == b) -> if (!(a == b))

Sometimes that is the case; other times, it's just a super convoluted
way of saying 'if (a)' when b = 0:

if (!1 == 0) -> if (0 == 0) -> if (true)

Alternatively:

if (!1 == 0) -> if (!!1) -> if (1)

Simplify these comparisons so that Clang doesn't complain.
