ASoC: soc-cache: Fix memory overflow in LZO initialization

The bitmap_zero() nbits argument was improperly set to reg_size
but the underlying buffer was bmp_size long.  This caused the memset
to zero past the end of the allocated buffer and into the kernel heap
causing strange kernel crashes sometimes by overwriting critical
kernel structures.
