iscsi tools: Convert '-r' argument to an integer before checking if it is a path

If there is a file in the CWD named '1' and you were trying to run
'iscsiadm -m session -r 1 ...', the command would fail with "1 is not a
directory".

Root cause: The code that parses the -r option's argument tries lstat(2)
first, falling back to atoi(3) only if lstat fails.

This change inverts the order of checks, first with strtol(3) to see if
the argument given is a positive integer, then falling back to lstat(2)
only if it is not.
