svc_bc_tcp_create() is a helper function that simply calls
svc_bc_create_socket() with an added IPPROTO_TCP argument.

svc_bc_create_socket() then checks that the protocol argument is indeed
IPPROTO_TCP.

This isn't necessary since svc_bc_tcp_create() is the only
svc_bc_create_socket() caller.  The next patch adds a second caller for
AF_VSOCK where IPPROTO_TCP will not be used.

Scrap this scheme and just call svc_bc_create_socket() directly.
