scsi: qla2xxx: Fix printk() format string

Printing a size_t value that is the result of the sizeof() operator
requires using the %z format string modifier to avoid a warning on 32-bit
architectures:

drivers/scsi/qla2xxx/qla_mid.c: In function 'qla_create_buf_pool':
drivers/scsi/qla2xxx/qla_mid.c:1094:51: error: format '%ld' expects argument of type 'long int', but argument 5 has type 'unsigned int' [-Werror=format=]
 1094 |                     "Failed to allocate buf_map(%ld).\n", sz * sizeof(unsigned long));
      |                                                 ~~^       ~~~~~~~~~~~~~~~~~~~~~~~~~~

      |                                                   long int   unsigned int
      |                                                 %d
