Subject: ceph: normalize 'delta' parameter usage in check_quota_exceeded
Git-commit: daa668fbacfdb9147b1828fc0f97b685bf4a51e3
Patch-mainline: v5.8-rc1
References: bsc#1172987

Function check_quota_exceeded() uses delta parameter only for the
QUOTA_CHECK_MAX_BYTES_OP operation.  Using this parameter also for
MAX_FILES will makes the code cleaner and will be required to support
cross-quota-tree renames.
