net: fec: properly guard irq coalesce setup

commit 7e6303567ce3ca506e4a2704e4baa86f1d8bde02 upstream.

Prior to the Fixes: commit, the initialization code went through the
same fec_enet_set_coalesce() function as used by ethtool, and that
function correctly checks whether the current variant has support for
irq coalescing.

Now that the initialization code instead calls fec_enet_itr_coal_set()
directly, that call needs to be guarded by a check for the
FEC_QUIRK_HAS_COALESCE bit.

Fixes: df727d4547de (net: fec: don't reset irq coalesce settings to defaults on "ip link up")
