[ Upstream commit ab14961d10d02d20767612c78ce148f6eb85bd58 ]
fec_enet_set_coalesce() validates the previously set params
and if they are within range proceeds to apply the new ones.
The new ones, however, are not validated. This seems backwards,
probably a copy-paste error?
Compile tested only.
Fixes: d851b47b22fc ("net: fec: add interrupt coalescence feature support")
