From: Eric Biggers <ebiggers@xxxxxxxxxx>
commit 7a0905caf5665be41094a6ceb5e9d2524de4627a upstream.
Commit 56541c7c4468 ("scsi: ufs: ufs-qcom: Switch to the new ICE API")
introduced an incorrect check of the algorithm ID into the key eviction
path, and thus qcom_ice_evict_key() is no longer ever called. Fix it.
