cifs: new nt status codes from MS-SMB2

Browse Source 
[ Upstream commit 7f738527a7a03021c7e1b02e188f446845f05eb6 ]

MS-SMB2 spec has introduced two new status codes,
STATUS_SERVER_UNAVAILABLE and STATUS_FILE_NOT_AVAILABLE
which are to be treated as retryable errors.

This change adds these to the available mappings and
maps them to Linux errno EAGAIN.
