Kees Cook 64b6deadc9 scsi: uapi: Replace 0-length array with flexible array
Zero-length arrays are deprecated[1]. Replace struct
fc_bsg_host_vendor_reply's "vendor_rsp" 0-length array with a flexible
array. Detected with GCC 13, using -fstrict-flex-arrays=3:

drivers/scsi/qla2xxx/qla_isr.c: In function 'qla25xx_process_bidir_status_iocb.isra':
drivers/scsi/qla2xxx/qla_isr.c:3117:54: warning: array subscript 0 is outside array bounds of '__u32[0]' {aka 'unsigned int[]'} [-Warray-bounds=]
 3117 |         bsg_reply->reply_data.vendor_reply.vendor_rsp[0] = rval;
      |         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~
