drivers/net/tlan.c: compilation warning fix
Add a check for the pci_register_driver() return value. Removed unused
variable pad_allocated.
The aim of this patch is to remove the following warning messages:
drivers/net/tlan.c: In function 'tlan_probe':
drivers/net/tlan.c:486: warning: ignoring return value of 'pci_register_driver', declared with attribute warn_unused_result
