[PATCH] fix oops in emu10k1_wavein_open() error recovery

If a large pci_alloc_consistent() GFP_ATOMIC allocation fails this driver's
recovery code will call emu10k1_wavein_close() far earlier than it should: it
goes splat in emu10k1_timer_uninstall().

Fix it by simply removing that call: we haven't allocated any resources yet
anyway.

Note that one of the callers of emu10k1_wavein_open(), emu10k1_audio_read()
will sit there stupidly retrying the open.  But it has a sleep in there so
something might eventually give way.
