scsi: qedi: Check for buffer overflow in qedi_set_path()

Browse source

Smatch complains that the "path_data->handle" variable is user controlled.
It comes from iscsi_set_path() so that seems possible.  It's harmless to
add a limit check.

The qedi->ep_tbl[] array has qedi->max_active_conns elements (which is
always ISCSI_MAX_SESS_PER_HBA (4096) elements).  The array is allocated in
the qedi_cm_alloc_mem() function.
