Subject: [PATCH] pxa168fb: fix release function mismatch in probe failure

The driver uses kfree() to release the resource allocated by
framebuffer_alloc(), which does not match.
Use framebuffer_release() instead to fix it.

Fixes: 638772c7553f ("fb: add support of LCD display controller on pxa168/910 (base layer)")
