[PATCH] remove check_region from drivers_scsi_cpqfcTSinit.c

From:  william stinson <wstinson@wanadoo.fr>

  this proposed patch for drivers/scsi/cpqfcTSinit.c scsi driver for
  Linux removes two calls to check_region using request_region instead

  This is patch number 28 in a series of check_region patches I am doing as
  part of the kernel janitors project.
