ANDROID: scsi: ufs: revise and fix custom keyslot manager support

UFSHCD_QUIRK_BROKEN_CRYPTO_CAPS really means
"override the blk_keyslot_manager", which (at least for now) handles
both the crypto capabilities and the actual keyslot management.
So give it a better name: UFSHCD_QUIRK_CUSTOM_KEYSLOT_MANAGER.

Also, fix ufshcd_init_crypto() to call hba->ksm.ksm_ll_ops.keyslot_evict
instead of using the standard key eviction procedure.  This is needed
when the blk_keyslot_manager is overridden with one that has
num_slots > 0 and uses a nonstandard key eviction procedure.

This patch, ANDROID-scsi-ufs-add-UFSHCD_QUIRK_BROKEN_CRYPTO_CAPS.patch,
and ANDROID-scsi-ufs-allow-for-there-to-be-no-keyslots.patch should all
be folded into one patch.
