Examples:
# scripts/scylla-jmx -l /usr/lib/scylla/jmx ""
Result: script stuck
# scripts/scylla-jmx "" -l /usr/lib/scylla/jmx
Unknown parameter: /usr/lib/scylla/jmx
Result: wrongly shift arguments
Above two problem caused by a redundant argument parse ("$PARAM_PORT"),
the variable isn't set, so it's a covert empty string. The others valid
9 options are all parsed with right case, and API_ADDR also be set by
other case path, so it's safe to remove $PARAM_PORT.
This patch removed the redundant argument, and skipped empty string in
arguments.
