nvmet-tcp: constify nvmet_tcp_ops

Browse Source 
nvmet_tcp_ops is never modified and can be made const to allow the
compiler to put it in read-only memory, as done in other transports.

Before:
   text    data     bss     dec     hex filename
  16164     160      12   16336    3fd0 drivers/nvme/target/tcp.o

After:
   text    data     bss     dec     hex filename
  16277      64      12   16353    3fe1 drivers/nvme/target/tcp.o
