net: always inline net_secret_init
Currently net_secret_init does not get inlined, so we always have a call to net_secret_init even in the fast path. Let's specify net_secret_init as __always_inline so we have the nop in the fast-path without the call to net_secret_init and the unlikely path at the epilogue of the function. jump_labels handle the inlining correctly.
