src/lib/config.c: fix parse_ul_sfx after refactoring

After commit e14a0127adf3813b7f06ada75d1e43c8c263d420
in function parse_twoul_sfx() 'ret' is no longer initialized to 0,
thus the function may return a random value, which could lead to errors
like this:

 Warning: too large value for NUMPROC=240:240 was truncated
 Invalid value for DISKINODES=200000:220000, skipped

Fix that.
