userns: Properly print bluetooth socket uids

With user namespace support enabled building bluetooth generated the warning.
net/bluetooth/af_bluetooth.c: In function ‘bt_seq_show’:
net/bluetooth/af_bluetooth.c:598:7: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 7 has type ‘kuid_t’ [-Wformat]

Convert sock_i_uid from a kuid_t to a uid_t before printing, to avoid
this problem.
