ALSA: emu10k1: Fix endianness annotations

The internal page tables are little endian, hence they should be
__le32 type.  This fixes the relevant sparse warning:
  sound/pci/emu10k1/emu10k1_main.c:2013:51: warning: incorrect type in assignment (different base types)
  sound/pci/emu10k1/emu10k1_main.c:2013:51:    expected unsigned int [usertype]
  sound/pci/emu10k1/emu10k1_main.c:2013:51:    got restricted __le32 [usertype]

No functional changes, just sparse warning fixes.
