[PATCH] remove check_region from drivers_isdn_hisax_avm_pci.c

  This patch for drivers/isdn/hisax/avm_pci.c isdn driver removes one
  call to check_region using request_region instead

  I don't have this hardware so patch is not tested. This patch removes all
  references to check_region in this driver.

  This is patch number 24 in a series of check_region patches I am doing as
  part of the kernel janitors project.
