scsi: mpi3mr: Use proper format specifier in mpi3mr_sas_port_add()

When building for a 32-bit platform such as ARM or i386, for which size_t
is unsigned int, there is a warning due to using an unsigned long format
specifier:

  drivers/scsi/mpi3mr/mpi3mr_transport.c:1370:11: error: format specifies type 'unsigned long' but the argument has type 'unsigned int' [-Werror,-Wformat]
   1369 |                         ioc_warn(mrioc, "skipping port %u, max allowed value is %lu\n",
        |                                                                                 ~~~
        |                                                                                 %u
   1370 |                             i, sizeof(mr_sas_port->phy_mask) * 8);
        |                                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Use the proper format specifier for size_t, %zu, to resolve the warning for
all platforms.
