phy: marvell: a3700-comphy: Fix out of bounds read

Browse source

[ Upstream commit e4308bc22b ]

There is an out of bounds read access of 'gbe_phy_init_fix[fix_idx].addr'
every iteration after 'fix_idx' reaches 'ARRAY_SIZE(gbe_phy_init_fix)'.

Make sure 'gbe_phy_init[addr]' is used when all elements of
'gbe_phy_init_fix' array are handled.
