cifs: set replay flag for retries of write command

Browse Source 
[ Upstream commit 4cdad80261 ]

Similar to the rest of the commands, this is a change
to add replay flags on retry. This one does not add a
back-off, considering that we may want to flush a write
ASAP to the server. Considering that this will be a
flush of cached pages, the retrans value is also not
honoured.
