avdevice/v4l2: fix potential memleak when allocating device buffers
In the loop which allocates the buffers for a V4L2 device, if failure
occurs for a certain buffer (e.g. 3rd of 4 buffers), then the previously
allocated buffers (and the buffer array) would not be free'd in
the mmap_init(). This would cause a leak.

This change handles the error cases of that loop to free all allocated
resources, so that when mmap_init() fails nothing is leaked.
