[PATCH 12/14] fbdev: efifb: fix memory leak in efifb_probe()

[Abdun Nihaal]

Since commit 73ce73c30ba9 ("fbdev: Transfer video= option strings to
caller; clarify ownership") the string returned from fb_get_options()
is expected to be freed by the caller, but the string is not freed in
efifb_probe(). Fix that by freeing the option string after setup.
