Masami Ichikawa 46862145d4 fbcon: Fix memory leak in fbcon_exit(). 
kmemleak reported a memory leak as below.

unreferenced object 0xffff880036ca84c0 (size 16):
  comm "swapper/0", pid 1, jiffies 4294877407 (age 4434.633s)
  hex dump (first 16 bytes):

    [<ffffffff812f201b>] fb_notifier_call_chain+0x1b/0x20

In this case ops->cursor_state.mask is allocated in bit_cursor() but
not freed in fbcon_exit(). So, fbcon_exit() needs to free buffer in its
process.
In the case, fbcon_exit() was called from fbcon_deinit() when driver
called remove_conflicting_framebuffers().
