use callout for request timeout, so that it could expire independantly 

of iod calling smb_iod_sendall()
g/c now unneeded request timeout expire check from smb_iod_sendall()

make it possible to override default request timeout - set timeout
value in smb_rq_init() to default value, caller can adjust the value
before calling smb_iod_sendrq(); value <=0  means no timeout
