Eliminate the follow smatch warning:
drivers/scsi/pm8001/pm8001_ctl.c:760 pm8001_update_flash() warn:
inconsistent indenting

Reported-by: Abaci Robot <abaci@linux.alibaba.com>
Signed-off-by: Yang Li <yang.lee@linux.alibaba.com>
---

  Changes in v2:
--According to Damien's suggestion
  1) Start multi-line comments with a line that has only "/*".
  2) Align the conditions together to make this code more readable.
  3) Using a local variable for value which is calculated too many times.

I think that the "= 0" is not needed.

I would move this line down, right above the "if" where the variable is
used.

While at it, please add spaces around the "-" and remove the unnecessary
parenthesis:

	if (loopcount - loopNumber == 1 && fc_len) {

With that fixed, looks good.
