[PATCH] [v3] mptcp: Fix duplicated argument in protocol.h

[Wan Jiabing]

Fix the following coccicheck warning:
./net/mptcp/protocol.h:36:50-73: duplicated argument to & or |

The OPTION_MPTCP_MPJ_SYNACK here is duplicate.
Here should be OPTION_MPTCP_MPJ_ACK.

Fixes: 74c7dfbee3e18 ("mptcp: consolidate in_opt sub-options fields in a bitmask")

Not sure what happen to my previous reply, most probably PEBKAC, sorry.

WRT this patch, note that the dup is harmless, as in the input path we
always use the mask and not the individual bit - vice versa in the
output path. Still the cleanup is worthy and patch LGTM.

Thank you for the patch!

It looks good to me too and MPTCP selftests are still happy with this patch.
