fbdev: vesafb: fix memory leak in vesafb_probe()

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
vesafb_probe(). Fix that by freeing the option string after setup.
