Maxim Mikityanskiy 73eeba71dc mptcp: Fix out of bounds when parsing TCP options
[ Upstream commit 07718be265680dcf496347d475ce1a5442f55ad7 ]

The TCP option parser in mptcp (mptcp_get_options) could read one byte
out of bounds. When the length is 1, the execution flow gets into the
loop, reads one byte of the opcode, and if the opcode is neither
TCPOPT_EOL nor TCPOPT_NOP, it reads one more byte, which exceeds the
length of 1.

This fix is inspired by commit 9609dad263 ("ipv4: tcp_input: fix stack
out of bounds when parsing TCP options.").
