Re: [PATCH][V3][net-next] net: sctp: fix array overrun read on sctp_timer_tbl

Table sctp_timer_tbl is missing a TIMEOUT_RECONF string so
add this in. Also compare timeout with the size of the array
sctp_timer_tbl rather than SCTP_EVENT_TIMEOUT_MAX.  Also add
a build time check that SCTP_EVENT_TIMEOUT_MAX is correct
so we don't ever get this kind of mismatch between the table
and SCTP_EVENT_TIMEOUT_MAX in the future.

Kudos to Marcelo Ricardo Leitner for spotting the missing string
and suggesting the build time sanity check.

Fixes CoverityScan CID#1397639 ("Out-of-bounds read")
