Subject: megaraid_sas: add missing curly braces in ioctl handler

From: Arnd Bergmann <[email protected]>

commit 3deb9438d34a09f6796639b652a01d110aca9f75 upstream.

gcc-6 found a dubious indentation in the megasas_mgmt_fw_ioctl function:

drivers/scsi/megaraid/megaraid_sas_base.c: In function 'megasas_mgmt_fw_ioctl':
drivers/scsi/megaraid/megaraid_sas_base.c:6658:4: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]

    kbuff_arr[i] = NULL;
    ^~~~~~~~~

drivers/scsi/megaraid/megaraid_sas_base.c:6653:3: note: ...this 'if' clause, but it is not
if (kbuff_arr[i])
^~

The code is actually correct, as there is no downside in clearing a NULL pointer again.

This clarifies the code and avoids the warning by adding extra curly braces.
