[PATCH] video: fbdev: pxa3xx_gcu: Fix some resource leak in an error handling path in 'pxa3xx_gcu_probe()'

[Christophe JAILLET]

If an error occurs in the loop where we call 'pxa3xx_gcu_add_buffer()',
any resource already allocated should be freed.

In order to fix it, add a call to 'pxa3xx_gcu_free_buffers()' in the error
handling path, as already done in the remove function.

Fixes: 364dbdf3b6c3 ("video: add driver for PXA3xx 2D graphics accelerator")
