smpp_smsc: Fix integer overflow in read return value and msgb_alloc()
The size parameter of msgb_alloc is uint16_t so any length value above
65535 will allocate a msgb with incorrect size.
This patch changes the type of rdlen and rc to ssize_t (the return value
of read) and guards against the read length being larger than
UINT16_MAX.
To reproduce the issue run:
echo -en "\x00\x01\x00\x01\x01" |socat stdin tcp:localhost:2775
