serial: earlycon: Skip parse_options() if empty string
Earlycon param strings of the form
earlycon=<name>
are rejected from parse_options() with an error (which, in turn,
results in a NULL argument for the setup() method options parameter).
Only pass non-empty string to parse_options(); this will enable
handling actual parse errors differently than expected and allow
formats.
