packet_loss macros quick fix

Due to device_perf table going away, this macro no longer functions as it did.
Use device status to make it somewhat functional until a better solution can be found.

     <description>Due to a bug, all manually set port speeds will need to be reconfigured. Likely they are set to 1 instead of the expected value. See https://github.com/librenms/librenms/pull/15238 for more information.</description>

+    <description>The packet loss macros were broken recently. The quick fix is to have them resemble device up/down, which is similar to how they would function if fping_options.count=1. Hopefully, they can be fixed in the future, but be aware their functionality is degraded in the meantime.</description>
