Avoid double lwp_exit() in eventswitch()

For the PTRACE_LWP_EXIT event, the eventswitch() call is triggered from
lwp_exit(). In the case of setting the program status to PS_WEXIT, do not
try to demise in place, by calling lwp_exit() as it causes panic.

In this scenario bail out from the function and resume the lwp_exit()
procedure.
