[linux-cifs-client] NOCMTIME and NOATIME

[Steve French (smfltc)]

Shirish noticed that the NOATIME and NOCMTIME flags that cifs sets in 
new inodes
in order to prevent writes of the clients file access and file 
modfication timestamps to the server
(we intended to use the servers instead) were getting overwritten in the 
VFS.

Fixing this should help performance and also help applications that are 
dependent on a more
consistent view of timestamps (if timestamps are sometimes from server 
and sometimes
from client setting them, presumably we have cases in which "time 
appears to go backwards" if
the time is off enough between client and server)
