cifs: Fix wrong return value checking when GETFLAGS

Browse Source 
[ Upstream commit 92bbd67a55fee50743b42825d1c016e7fd5c79f9 ]

The return value of CIFSGetExtAttr is negative, should be checked
with -EOPNOTSUPP rather than EOPNOTSUPP.

Fixes: 64a5cfa6db ("Allow setting per-file compression via SMB2/3")
