Subject: [PATCH -next v3] scsi: pm8001: clean up some inconsistent indentin

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

  Changes in v3:
--According to Damien's suggestion
  1) "u32 fc_len = 0;" -> "u32 fc_len;".
  2) Add spaces around the "-" and remove the unnecessary parenthesis.
  3) Move "fc_len = (partitionSize + HEADER_LEN) % IOCTL_BUF_SIZE;"down,
     right above the "if" where the variable is used.
