ALSA: fm801: Initialize chip after IRQ handler is registered 

The commit b56fa687e0 ("ALSA: fm801: detect FM-only card earlier")
rearranged initialization calls, i.e. it makes snd_fm801_chip_init() to
be called before we register interrupt handler and set PCI bus
mastering.

Somehow it prevents FM801-AU to work properly. Thus, partially revert
initialization order changed by commit mentioned above.
