[PATCH][next] drm/vmwgfx: Fix memory leak of object fifo on error return

[Colin King <colin.king@xxxxxxxxxxxxx>]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

In the case where fifo->static_buffer fails to be allocated the
error return path neglects to kfree the fifo object. Fix this by
adding in the missing kfree.

Addresses-Coverity: ("Resource leak")
Fixes: 2cd80dbd3551 ("drm/vmwgfx: Add basic support for SVGA3")
