smb: client: allocate struct sess_data on the stack

CIFS_SessSetup() kzalloc()s struct sess_data only to run a synchronous
state machine and free it before returning; the object never escapes the
function.  At 96 bytes it fits comfortably on the stack even under
CONFIG_FRAME_WARN=1024, so drop the allocation and its failure path.

memzero_explicit() preserves the kfree_sensitive() scrubbing.
