cifs: fix a memleak in cifs_setattr_nounix()
Andrew Hendry reported a kmemleak warning in 2.6.37-rc1 while editing a
text file with gedit over cifs.
unreferenced object 0xffff88022ee08b40 (size 32):
comm "gedit", pid 2524, jiffies 4300160388 (age 2633.655s)

The commit 1025774c that removed inode_setattr() seems to have introduced this
memleak by returning early without freeing 'full_path'.
