V4L/DVB (6305): V4L: videobuf-core.c avoid NULL dereferences in videobuf-core
The return value of videobuf_alloc() is unchecked but this function will
return NULL on an error. Check for NULL and make videobuf_reqbufs()
return the number of successfully allocated buffers.
Also, fix saa7146_video.c and bttv-driver.c to use this returned
buffer count.
Tested against the vivi driver. Not tested against saa7146 or bt8xx
devices.
