Amos Kong f4ef4a5a3e scripts: process empty string in arguments
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.
