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

[ Upstream commit 499a2c41b9 ]

'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.

Fixes: 77e196752b ("[ARM] pxafb: allow video memory size to be configurable")
