[PATCH] video: pxafb: Fix the function used to balance a 'dma_alloc_coherent()' call

[Christophe JAILLET]

'dma_alloc_coherent()' must be balanced by a call to 'dma_free_coherent()'
not 'dma_free_wc()'.
The correct dma_free_ function is already used in the error handling path
of the probe function.
