pxa168fb: Fix the function used to release some memory in an error handling path
In the probe function, some resources are allocated using 'dma_alloc_wc()', they should be released with 'dma_free_wc()', not 'dma_free_coherent()'. We already use 'dma_free_wc()' in the remove function, but not in the error handling path of the probe function. Also, remove a useless 'PAGE_ALIGN()'. 'info->fix.smem_len' is already PAGE_ALIGNed.
