net: mana: Move current_speed debugfs file to mana_init_port()

[ Upstream commit 3b7c7fc ]

Move the current_speed debugfs file creation from mana_probe_port() to
mana_init_port(). The file was previously created only during initial
probe, but mana_cleanup_port_context() removes the entire vPort debugfs
directory during detach/attach cycles. Since mana_init_port() recreates
the directory on re-attach, moving current_speed here ensures it survives
these cycles.
