extmod/modframebuf: Fix FrameBuffer get-buffer implementation.

Browse Source 
This wasn't correctly accounting for the bits-per-pixel and was returning a
bufinfo struct with the incorrect length.  Instead, just forward directly
to the underlying buffer object.

Fixes issue #12563.

This work was funded through GitHub Sponsors.
