Modified Files:
src/sbbs3/mailsrvr.cpp sbbscon.c
Log Message:
mailsrvr,sbbscon: suppress more link_list helper LOCK/SLEEP false-positives (CIDs 631134, 631143, 631144)

Same pattern as services.cpp commit dc6482fa5: loginBanned() and the
listX helpers acquire+release link_list mutexes internally, but
Coverity's inter-procedural lock tracking misses the matching unlock
and reports phantom LOCK/SLEEP issues at the call sites.

CID 631134: loginBanned LOCK in pop3_client_thread
CID 631143: sockprintf SLEEP after loginBanned in pop3_client_thread
CID 631144: listFindTaggedNode LOCK while listLock held in client_on
(recursive list mutex, see link_list.h:99)
