SELinux: avtab.c whitespace, syntax, and static declaraction cleanups

This patch changes avtab.c to fix whitespace and syntax issues.  Things that
are fixed may include (does not not have to include)

whitespace at end of lines
spaces followed by tabs
spaces used instead of tabs
spacing around parenthesis
locateion of { around struct and else clauses
location of * in pointer declarations
removal of initialization of static data to keep it in the right section
useless {} in if statemetns
useless checking for NULL before kfree
fixing of the indentation depth of switch statements
and any number of other things I forgot to mention
