ixgbe: fix poll loop for FDIRCTRL.INIT_DONE bit

Browse source 
The loop in ixgbe_reinit_fdir_tables_82599() only polls for up to 100us
resulting in failures to update the FDIR filter table at 1Gbps and 10Gbps
when under load.

The poll times for FDIRCTRL.INIT_DONE are 55us, 550us and 5.5ms for 10Gbps,
1Gbps and 100Mbps respectively.

This patch sets the wait time to be the same as in ixgbe_fdir_enable_82599()
