[PATCH] adm80211: Removed unused 'io_addr' 'mem_addr' variables

[Kirtika Ruchandani <kirtika.ruchandani@gmail.com>]

Initial commit cc0b88cf5ecf ([PATCH] Add adm8211 802.11b wireless driver)
introduced variables mem_addr and io_addr in adm80211_probe() that are
set but not used. Compiling with W=1 gives the following warnings,
fix them.

drivers/net/wireless/admtek/adm8211.c: In function ‘adm8211_probe’:
drivers/net/wireless/admtek/adm8211.c:1769:15: warning: variable ‘io_addr’ set but not used [-Wunused-but-set-variable]
  unsigned int io_addr, io_len;
               ^
drivers/net/wireless/admtek/adm8211.c:1768:16: warning: variable ‘mem_addr’ set but not used [-Wunused-but-set-variable]
  unsigned long mem_addr, mem_len;
                ^

These are harmless warnings and are only being fixed to reduce the
noise with W=1 in the kernel. The calls to pci_resource_start do not
have any side-effects and are safe to remove.
