cache_mngr: Fix assignment of error code in nl_cache_mngr_alloc()
cache_mngr: Fix assignment of error code in nl_cache_mngr_alloc()

In the current form, the parentheses in these two if (...) statements
lead to err being assigned the result of nl_connect(...) < 0 and
nl_socket_set_nonblocking(...) < 0 instead of the return value of these
functions. Adjust the parentheses to assign the returned error code to
err.
