Subject: [PATCH net] bnxt_en: eliminate the compile warning in bnxt_request_irq due to CONFIG_RFS_ACCEL
From: Jason Xing <kernelxing@...cent.com>
I received a kernel-test-bot report[1] that shows the
[-Wunused-but-set-variable] warning. Since the previous commit[2] I made
gives users an option to turn on and off the CONFIG_RFS_ACCEL, the issue
then can be discovered and reproduced. Move the @i into the protection
of CONFIG_RFS_ACCEL.

All warnings (new ones prefixed by >>):
drivers/net/ethernet/broadcom/bnxt/bnxt.c: In function 'bnxt_request_irq':
>> drivers/net/ethernet/broadcom/bnxt/bnxt.c:10703:9: warning: variable 'j' set but not used [-Wunused-but-set-variable]
10703 | int i, j, rc = 0;
