[ Upstream commit e1a8805e5d263453ad76a4f50ab3b1c18ea07560 ]

Fix incorrect argument order in devm_kcalloc() when allocating port->phys.
The original call used sizeof(phy) as the number of elements and
port->lanes as the element size, which is reversed.  While this happens to
produce the correct total allocation size with current pointer size and
lane counts, the argument order is wrong.
