Partially reworked r219042.
The reason for this is a bug at ktrops() where process dereferenced
without having a lock. This might cause a panic if ktrace was runned
with -p flag and the specified process exited between the dropping
a lock and writing sv_flags.

Since it is impossible to acquire sx lock while holding mtx switch
to use asynchronous enqueuerequest() instead of writerequest().

Rename ktr_getrequest_ne() to more understandable name [1].
