efi/libstub: fix efi_parse_options() ignoring the default command line
[ Upstream commit aacfa0ef247b0130b7a98bb52378f8cd727a66ca ]
efi_convert_cmdline() always returns a size of at least 1 because it
counts the NUL terminator, so the "cmdline_size == 0" condition is never
satisfied.
Change it to check if the string starts with a NUL character to get the
intended behavior: to use CONFIG_CMDLINE when load_options_size == 0.
Fixes: 60f38de7a8d4 ("efi/libstub: Unify command line param parsing")
