x86/ldt: Initialize the context lock for init_mm

Browse source

The mutex mm->context->lock for init_mm is not initialized for init_mm.
This wasn't a problem because it remained unused. This changed however
since commit
	4fc19708b1 ("x86/alternatives: Initialize temporary mm for patching")

Initialize the mutex for init_mm.
