CIFS: avoid using MID 0xFFFF
commit 03d9a9fe3f3aec508e485dd3dcfa1e99933b4bdb upstream.
According to MS-CIFS specification MID 0xFFFF should not be used by the
CIFS client, but we actually do. Besides, this has proven to cause races
leading to oops between SendReceive2/cifs_demultiplex_thread. On SMB1,
MID is a 2 byte value easy to reach in CurrentMid which may conflict with
an oplock break notification request coming from server
