Subject: sierra_net: Skip validating irrelevant fields for IDLE LSIs

From: Stefan Br�ns <[email protected]>

[ Upstream commit 764895d3039e903dac3a70f219949efe43d036a0 ]

When the context is deactivated, the link_type is set to 0xff, which triggers a warning message, and results in a wrong link status, as the LSI is ignored.
