[PATCH AUTOSEL 4.4 16/30] video: goldfishfb: fix memory leak on driver remove

[Sasha Levin]

From: Anton Vasilyev <vasil...@ispras.ru>

[ Upstream commit 5958fde72d04e7b8c6de3669d1f794a90997e3eb ]

goldfish_fb_probe() allocates memory for fb, but goldfish_fb_remove() does
not have deallocation of fb, which leads to memory leak on probe/remove.

The patch adds deallocation into goldfish_fb_remove().
