[PATCH 4/6] [SRU][K] ALSA: pdaudiocf: Drop superfluous GFP setup

[Koba Ko]

From: Takashi Iwai <tiwai at suse.de>

BugLink: https://bugs.launchpad.net/bugs/2009136

The extra setup with GFP_DMA32 is superfluous for this driver.  The
whole operation is a simple copy loop, and there is no memory address
restriction at all.  Drop the useless GFP setup.
