fbcon: check return value of con2fb_acquire_newinfo()
[ Upstream commit 011a0502801c8536f64141a2b61362c14f456544 ]
If fbcon_open() fails when called from con2fb_acquire_newinfo() then
info->fbcon_par pointer remains NULL which is later dereferenced.
Add check for return value of the function con2fb_acquire_newinfo() to
avoid it.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
