[PATCH] uml: fix host LDT lookup initialization locking, try 2
Add some locking to host_ldt_entries to prevent racing when reading LDT
information from the host.
The locking is somewhat more careful than my previous attempt. Now, only
the check of host_ldt_entries is locked. The lock is dropped immediately
afterwards, and if the LDT needs initializing, that (and the memory
allocations needed) proceed outside the lock.
Also fixed some style violations.
