The qatomic_cmpxchg() and qatomic_cmpxchg__nocheck() macros have
a comment that reads:
Returns the eventual value, failed or not
This is somewhere between cryptic and wrong, since the value actually
returned is the value that was in memory before the cmpxchg. Reword
to match how we describe these macros in atomics.rst.
