octeontx2-af: Increase link credit restore polling timeout

It's been observed that sometimes link credit restore takes
a lot of time than the current timeout. This patch increases
the default timeout value and return the proper error value
on failure.

Fixes: 1c74b891 ("octeontx2-af: Wait for TX link idle for credits change")
