[PATCH v2 17/30] cxlflash: Fix async interrupt bypass logic

[Matthew R. Ochs]

A bug was introduced earlier in the development cycle when cleaning
up logic statements. Instead of skipping bits that are not set, set
bits are skipped, causing async interrupts to not be handled correctly.

To fix, simply add back in the proper evaluation for an unset bit.
