cifs: Fix use-after-free on mid_q_entry With CIFS_DEBUG_2 enabled, additional debug information is tracked inside each mid_q_entry struct, however cifs_save_when_sent may use the mid_q_entry after it has been freed from the appropriate callback if the transport layer has very low latency. Holding the srv_mutex fixes this use-after-free, as cifs_save_when_sent is called while the srv_mutex is held while the request is sent. Signed-off-by: Christopher Oo <t-chriso@microsoft.com>
