MAINTAINERS: adjust to livepatch .klp.arch removal
Commit
1d05334d2899 ("livepatch: Remove .klp.arch") removed
arch/x86/kernel/livepatch.c, but missed to adjust the LIVE PATCHING entry
in MAINTAINERS.
Since then, ./scripts/get_maintainer.pl --self-test=patterns complains:
warning: no file matches F: arch/x86/kernel/livepatch.c
So, drop that obsolete file entry in MAINTAINERS.
Fixes: 1d05334d2899 ("livepatch: Remove .klp.arch")
