[PATCH v2] ceph/001: skip metrics check if no copyfrom mount option is used

["Luís Henriques" <lhenriques@suse.de>]

Checking the metrics is only valid if 'copyfrom' mount option is
explicitly set, otherwise the kernel won't be doing any remote object
copies.  Fix the logic to skip this metrics checking if 'copyfrom' isn't
used.

Changes since v1:
- Quoted 'hascopyfrom' variable in 'if' statement; while there, added
  quotes to the 'if' statement just above.
