fbdev: efifb: fix memory leak in efifb_probe()

Browse Source 
Since commit 73ce73c30b ("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.
