LU-17015 sec: fix PTLRPC_CTX_STATUS_MASK

PTLRPC_CTX_STATUS_MASK should not include PTLRPC_CTX_NEW_BIT, which is
a bit index and not a value. Also, according to code in
sptlrpc_req_refresh_ctx():
	if (unlikely(test_bit(PTLRPC_CTX_NEW_BIT, &ctx->cc_flags))) {
	   if (ctx->cc_ops->refresh)
	      ctx->cc_ops->refresh(ctx);
	}
a context needs to be refreshed if it has the PTLRPC_CTX_NEW_BIT bit.
So the function to check if context is refreshed, cli_ctx_is_refreshed
should not return true if the PTLRPC_CTX_NEW_BIT bit is set.

In the end, do not replace PTLRPC_CTX_NEW_BIT with anything else in
PTLRPC_CTX_STATUS_MASK. Having PTLRPC_CTX_NEW_BIT was a no-op (bitwise
OR with 0), but this was working as expected. Just cleanup the code to
avoid headaches.
