scsi: csiostor: Adjust indentation in csio_device_reset

Clang warns:

../drivers/scsi/csiostor/csio_scsi.c:1386:3: warning: misleading
indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
         csio_lnodes_exit(hw, 1);
         ^
../drivers/scsi/csiostor/csio_scsi.c:1382:2: note: previous statement is
here
        if (*buf != '1')
        ^
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.
