[PATCH] smbfs: double free memory corruption
smbfs allocates rq_trans2buffer to handle server's multi transaction2 response messages. As struct smb_request may be reused, rq_trans2buffer is freed before each new request. However if last servers's response is not multi but single trans2 message then new rq_trans2buffer is not allocated but last smb_rput still tries to free it again. To prevent this issue rq_trans2buffer pointer should be set to NULL after kfree.
