nvme-multipath: require exact iopolicy names for module parameter

The iopolicy module parameter uses strncmp prefix matching, so values
like "numax" are accepted as "numa".  The per-subsystem sysfs attribute
already requires an exact match via sysfs_streq().  Parse both through
a shared helper so invalid values are rejected consistently.
