For the case !CONFIG_DM_VERITY_VERIFY_ROOTHASH_SIG, declare the functions verity_verify_root_hash(), verity_verify_is_sig_opt_arg(), verity_verify_sig_parse_opt_args() and verity_verify_sig_opts_cleanup() as inline to avoid a "no previous prototype for xxx" compilation warning when compiling with W=1.
