The following changes are a set of miscellaneous fixes that makes
the ucount code a little bit easier to read. There are all things
that I ran into while helping hunt the crazy reference count
bug.

I am aiming these at the next merge window and 5.16 rather than bug
fixes to get into the current 5.15.

Eric W. Biederman (4):
ucounts: In set_cred_ucounts assume new->ucounts is non-NULL
ucounts: Remove unnecessary test for NULL ucount in get_ucounts
ucounts: Add get_ucounts_or_wrap for clarity
ucounts: Use atomic_long_sub_return for clarity
