mptcp: fix bogus socket flag values
Dan Carpenter reports static checker warnings due to bogus BIT() usage:
net/mptcp/subflow.c:571 subflow_write_space() warn: test_bit() takes a bit number
net/mptcp/subflow.c:694 subflow_state_change() warn: test_bit() takes a bit number
net/mptcp/protocol.c:261 ssk_check_wmem() warn: test_bit() takes a bit number
[..]
This is harmless (we use bits 1 & 2 instead of 0 and 1), but would
break eventually when adding BIT(5) (or 6, depends on size of 'long').
Just use 0 and 1, the values are only passed to test/set/clear_bit
functions.
Fixes: 648ef4b88673 ("mptcp: Implement MPTCP receive path")
