  fsverity: simplify fsverity_get_digest() (2022-11-29 21:07:41 -0800)

----------------------------------------------------------------

The main change this cycle is to stop using the PG_error flag to track
verity failures, and instead just track failures at the bio level.  This
follows a similar fscrypt change that went into 6.1, and it is a step
towards freeing up PG_error for other uses.

There's also one other small cleanup.
