RFA: patch to thread_db_kill


The attached patch removes a call in thread_db_kill() which attempts
to fetch the lwp for the inferior_ptid.  This call causes a problem
if the application is already killed becase an error will occur trying
to fetch information from libthread_db in thread_db_get_info().  This in
turn causes an error() call in thread_db_get_info() which throws us back to the
gdb prompt.  When we are trying to quit gdb, this keeps us from exiting.

The lower-level lin-lwp layer kill function does not use the inferior_ptid.

Ok to commit?
