x86/microcode: Adjust late loading result reporting message

Browse Source 
[ Upstream commit 6eab3abac7043226e5375e9ead0c7607ced6767b ]

During late microcode loading, the "Reload completed" message is issued
unconditionally, regardless of success or failure.

Adjust the message to report the result of the update.
