udev: Fix SIGSEGV in AlternativeNamesPolicy handling

The function sd_device_get_property_value has some paths where it exits without
touching the n pointer. In those cases, n remained uninitialized until it was
eventually read inside isempty where it caused the segmentation fault.

Fixes #15078

(cherry picked from commit 61fd7d6720c562c88ab79062ff8d131e5e3c7b1b)
