Subject: [PATCH] RH: mpathconf: correctly handle spaces after option names
mpathconf was either accepting any number of spaces, including zero,
after option names, or it was only accepting one space. It should
accept one or more spaces. Also, fix enable_foreign handling. It was
still working like it did in RHEL8, where the default was to enable
all foreign devices.
