LU-1854 ptlrpc: track culled request seq

Ptlrpc service should track highest culled request-seq by storing
it in ptlrpc_servce_part::scp_hist_seq_culled, however, there is
a missed case in ptlrpc_server_drop_request(): if rq_reply_state of
the request is pre-allocated and it should be freed immediately,
ptlrpc_server_drop_request() will unlink the request from history
list w/o track sequence number, and it can be the reason of
hitting LASSERT while reading req_history.

LU-1095 debug: quiet unnecessary console chatter

Quiet warning when configuring non-default CPT partitions, since this
will happen whenever the module parameter is changed.  Only complain
if the number of partitions is more than the number of cores, or if
it is more than 4x the recommended number.

Running racer.sh provokes a lot of messages from mdd_readdir(),
because it is doing "ls" in a directory that has been unlinked.
This is legal under POSIX and should not generate a console message.
