DeleteMidQEntry() was just a proxy for cifs_mid_q_entry_release().

Remove DeleteMidQEntry(), rename cifs_mid_q_entry_release() to
cifs_release_mid().

Also rename the kref_put() callback _cifs_mid_q_entry_release to
__cifs_release_mid.

Update callers to cifs_mid_q_entry_release and DeleteMidQEntry to use
cifs_release_mid.

How about simple change to this to remove "cifs" (since not smb1
specific) and call it something like:
  "release_mid_q_entry" or "mid_q_entry_release" ?

could also change AllocMidQEntry to something similar in the same
patch (it is trivial,
only used in 3 places) to be more consistent, easier to read:
   "alloc_mid_q_entry" (or "mid_q_entry_alloc")
