In the recent fix commit eda80d7c9c4d ("ALSA: memalloc: Fix regression
with SNDRV_DMA_TYPE_CONTINUOUS"), we replaced the pfn argument of the
remap_page_pfn() call from the uninitialized dmab->addr.  It was the
right fix, but it'd be more generic if we actually initialize
dmab->area for SNDRV_DMA_TYPE_CONTINOUS, too.  e.g. the field is used
in the common snd_sgbuf_get_addr(), too.
This patch adds the initialization of addr field and does revert of
the previous change to refer to it again in the mmap call.

Scratch this one, an old patch was submitted wrongly.
Will resubmit the right one.
