Tetsuo Handa 3c3bfb8586 fbdev: fbcon: release buffer when fbcon_do_set_font() failed 
syzbot is reporting memory leak at fbcon_do_set_font() [1], for
commit a5a923038d ("fbdev: fbcon: Properly revert changes when
vc_resize() failed") missed that the buffer might be newly allocated
by fbcon_set_font().
