cifs: Fix FALLOC_FL_INSERT_RANGE by setting i_size after EOF moved
Fix the cifs filesystem implementations of FALLOC_FL_INSERT_RANGE, in
smb3_insert_range(), to set i_size after extending the file on the server
and before we do the copy to open the gap (as we don't clean up the EOF
marker if the copy fails).
Fixes: 7fe6fe95b936 ("cifs: add FALLOC_FL_INSERT_RANGE support")
