  mtd: nand: pxa3xx: Allocate data buffer on detected flash size

the way the buffer is allocated was changed: the first READ_ID is issued
with a small kmalloc'ed buffer. Only once the flash page size is detected
the DMA buffers are allocated, and info->use_dma is set.

Currently, if the device detection fails, the driver checks the 'use_dma'
module parameter and tries to release unallocated DMA resources.

Fix this by checking the proper indicator of the DMA allocation, which
is 'info->use_dma'.
