[PATCH iwl-next] ixgbe: remove ixgbe_ping_all_vfs() from watchdog link-up handler

From: Sebastian Basierski <redacted>

When multiple VFs are brought up simultaneously, a VF can receive a
CTS (Clear To Send) mailbox message instead of the expected RESET |
(N)ACK response, because the watchdog is sending a gratuitous ping
right as the VF mailbox transaction is in progress.

Remove the ixgbe_ping_all_vfs() call from ixgbe_watchdog_link_is_up().
Link-state changes are already communicated to VFs through the normal
mailbox protocol; the extra ping here is redundant and races with VF
initialization.
