	smb: enable reuse of deferred file handles for write operations
Previously, deferred file handles were reused only for read operations, this commit extends to reusing deferred handles for write operations. By reusing these handles we can reduce the need for open/close operations over the wire. Signed-off-by: Bharath SM <bharathsm@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com>
