scsi: mpi3mr: Fix buffer overflow in the BSG target device map
The size of the target device map buffer is held in a u16 while the number
of devices it is derived from is not bounded to fit. With enough devices
the size wraps, a short buffer is allocated, and the loop that fills it
writes past the end.
Do the calculation in size_t.
