[PATCH iproute2-next 6/7] devlink: Add fflush() to print functions

[Ido Schimmel]

From: Ido Schimmel <ido...@mellanox.com>

Similar to commit 09e0528cf977 ("ip: mroute: add fflush to
print_mroute"), we need to add fflush() to the print functions to get
the following to work:

# devlink mon &> log

Without it, stdout output is buffered and not written to the disk.

This is useful when writing tests that rely on devlink-monitor output.
