net: Implement net_dbg_ratelimited() for CONFIG_DYNAMIC_DEBUG case
Prior to commit d92cff89a0c8 ("net_dbg_ratelimited: turn into no-op
when !DEBUG") the implementation of net_dbg_ratelimited() was buggy
for both the DEBUG and CONFIG_DYNAMIC_DEBUG cases.
The bug was that net_ratelimit() was being called and, despite
returning true, nothing was being printed to the console. This
resulted in messages like the following -
"net_ratelimit: %d callbacks suppressed"
with no other output nearby.
After commit d92cff89a0c8 ("net_dbg_ratelimited: turn into no-op when
!DEBUG") the bug is fixed for the DEBUG case. However, there's no
output at all for CONFIG_DYNAMIC_DEBUG case.
This patch restores debug output (if enabled) for the
CONFIG_DYNAMIC_DEBUG case.
Add a definition of net_dbg_ratelimited() for the CONFIG_DYNAMIC_DEBUG
case. The implementation takes care to check that dynamic debugging is
enabled before calling net_ratelimit().
Fixes: d92cff89a0c8 ("net_dbg_ratelimited: turn into no-op when !DEBUG")
