octeontx2-af: Increase link credit restore polling timeout
[ Upstream commit 1581d61b42d985cefe7b71eea67ab3bfcbf34d0f ]
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: 1c74b89171c3 ("octeontx2-af: Wait for TX link idle for credits change")
