media: pci: cx23885: replace BUG with error return

Browse Source 
[ Upstream commit 2e1796fd4904fdd6062a8e4589778ea899ea0c8d ]

It was completely unnecessary to use BUG in buffer_prepare().
Just replace it with an error return. This also fixes a smatch warning:

drivers/media/pci/cx23885/cx23885-video.c:422 buffer_prepare() error: uninitialized symbol 'ret'.
