net/txgbe: fix use-after-free on remove

[ upstream commit 0105788ebac6c796f30361912377550207084a17 ]

When cleaning up NIC's interrupts, it is possible to add some alarms
at the same time. However, if these alarms are not canceled, it may
cause use-after-free problems. Therefore, after cleaning up NIC's
interrupts, these alarms should also be canceled.

Fixes: d3bb4a04eac1 ("net/txgbe: add SFP hotplug identification")
Fixes: e0d876e ("net/txgbe: support device stop and close")
