staging: lustre: clio: remove mtime check in vvp_io_fault_start() 



In fault IO initialization, inode's mtime is saved, and after
getting locks, when the IO is about to start, vvp_io_fault_start()
checks the mtime's intactness.

It's a false alarm, since the timestamp from MDS could be stale,
we maintain mtime mainly on OST objects, and if the check in
vvp_io_fault_start() happens before mtime on OST objects are merged,
it will get wrong timestamp from the inode, even the timestamp it
fetched in vvp_io_fault_init() could be wrong in the first place.

This patch remove the mtime check in vvp_io_fault_start().
