mtd: nand: pxa3xx: Use info->use_dma to release DMA resources
In commit: commit 62e8b851783138a11da63285be0fbf69530ff73d Author: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Date: Fri Oct 4 15:30:38 2013 -0300 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'.
