uaccess: fix type mismatch warnings from access_ok()

Browse Source 
[ Upstream commit 23fc539e81 ]

On some architectures, access_ok() does not do any argument type
checking, so replacing the definition with a generic one causes
a few warnings for harmless issues that were never caught before.

Fix the ones that I found either through my own test builds or
that were reported by the 0-day bot.
