Jose E. Marchesi 756e34da53 bpf: fix constraint in test_tcpbpf_kern.c
GCC emits a warning:

  progs/test_tcpbpf_kern.c:60:9: error: ‘op’ is used uninitialized [-Werror=uninitialized]

when an uninialized op is used with a "+r" constraint.  The + modifier
means a read-write operand, but that operand in the selftest is just
written to.

This patch changes the selftest to use a "=r" constraint.  This
pacifies GCC.

Tested in bpf-next master.
No regressions.
