tcp/dccp: fix old style declarations

I’m using the compilation flag -Werror=old-style-declaration, which
requires that the “inline” word would come at the beginning of the code
line.

$ make drivers/net/ethernet/intel/e1000e/e1000e.ko
...
include/net/inet_timewait_sock.h:116:1: error: ‘inline’ is not at
beginning of declaration [-Werror=old-style-declaration]
static void inline inet_twsk_schedule(struct inet_timewait_sock *tw, int
timeo)

include/net/inet_timewait_sock.h:121:1: error: ‘inline’ is not at
beginning of declaration [-Werror=old-style-declaration]
static void inline inet_twsk_reschedule(struct inet_timewait_sock *tw,
int timeo)
