staging: fbtft: core: fix potential memory leak in fbtft_probe_common()

fbtft_probe_common() allocates a memory chunk for "info" with
fbtft_framebuffer_alloc(). When "display->buswidth == 0" is true, the
function returns without releasing the "info", which will lead to a
memory leak.

Fix it by calling fbtft_framebuffer_release() when "display->buswidth
== 0" is true.
