scsi: qla4xxx: Adjust indentation in qla4xxx_mem_free

Clang warns:

../drivers/scsi/qla4xxx/ql4_os.c:4148:3: warning: misleading
indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
         if (ha->fw_dump)
         ^
../drivers/scsi/qla4xxx/ql4_os.c:4144:2: note: previous statement is
here
        if (ha->queues)
        ^
1 warning generated.

This warning occurs because there is a space after the tab on this
line.  Remove it so that the indentation is consistent with the Linux
kernel coding style and clang no longer warns.
