[ Upstream commit e4b6135134a75f530bd634ea7c168efaf0f9dff3 ]

Some of the sequence numbers are printed as the negative ones in the debug
log:

[   46.250932] MPTCP: DSS

[   46.251343] MPTCP: msk=00000000ec44a129 ssk=00000000f7abd481 sending dfrag at seq=-1658937016627538668 len=100 already sent=0
[   46.251360] MPTCP: data_seq=16787807057082012948 subflow_seq=1 data_len=100 dsn64=1

This patch used the format specifier %u instead of %d for the unsigned int
values to fix it.
