lvs: if lost misc check child register checker agagin
issue: misc check_child_thread timeout and remove child_pid
form rb_data, timeout callback of check_child_thread is not be
called, if at this time misc script done and exit, and child
termination will do nothing because child_pid was remove form
rb_data. in this case timeou callback will not register checker
again, the checker will lost.
fix: if lost misc check child register checker again

commit e2b4d108d68ada3af8ad437e2e291fcac1fd0ff7

Date: Tue Oct 20 11:24:48 2020 +0100
ipvs: Allow real servers to be specified with a weight of 0
This currently only really makes sense when also having a FILE_CHECK
with non-zero weight configured, or a MISC_CHECK with "misc_dynamic",
since otherwise there is no way that the weight of the real server can
be changed to be non-zero.
