rt2x00_pci: Fix interrupt handler name (visible at /proc/interrupts)

Currently driver name is wrong. PCI device address is visible at
/proc/interrupts instead of the name:

 43:    124      0      0      0   PCI-MSI-edge    rtsx_pci
 44:    384      0      0      0   PCI-MSI-edge    snd_hda_intel
 45:  25096      0      0      0   PCI-MSI-edge    0000:01:00.0
                                                   ^^^^^^^^^^^^

So, pass the right name. rt2x00_ops->name contains KBUILD_MODNAME
and good for that, so pass it.

Handler names will be "rt2500pci", "rt2500pci" etc.
