tcp: tcp_check_req() can be called from process context
This is a follow up of commit 0a375c822497 ("tcp: tcp_rtx_synack()
can be called from process context").
Frederick Lawler reported another "__this_cpu_add() in preemptible"
warning caused by the same reason.
In my former patch I took care of tcp_rtx_synack()
but forgot that tcp_check_req() also contained some SNMP updates.
Note that some parts of tcp_check_req() always run in BH context,
I added a comment to clarify this.
Fixes: 8336886f786f ("tcp: TCP Fast Open Server - support TFO listeners")
