verity: use atomic_set instead of atomic_cmpxchg in read_completed

When moving from the PENDING to READY state it is sufficient to use
an atomic_set since we know the previous state MUST have been
PENDING. In addition, there is a BUG_ON which verifies this.

BUG=9752
TEST=Ran tests in verity.git. Ran platform_DMVerityCorruption on H/W.
