Move fib_rte_to_nh_flags() from net/route_var.h to net/route/nhop_ctl.c.

Browse Source 
No functional changes.
Initially this function was created to perform runtime flag conversions
 for the previous incarnation of fib lookup functions. As these functions
 got deprecated, move the function to the file with the only remaining
 caller. Lastly, rename it to convert_rt_to_nh_flags() to follow the
 naming notation.
