dht: add FOP check to dht_file_setattr_cbk

Problem:
bug-797171.7 loaded error-gen xlator on the brick which sent EBADF for a
non fd-based fop, namely setattr. This caused
dht_check_and_open_fd_on_subvol_task() to crash as local->fd was NULL.

Fix:
Call dht_check_and_open_fd_on_subvol_task() from dht_file_setattr_cbk
only for dht_fsetattr and not dht_setattr or dht_setattr2
