[PATCH v3 05/25] net/axgbe: disable interrupts during device removal

[Venkat Kumar Ande]

From: Venkat Kumar Ande <VenkatKumar.Ande at amd.com>

Hardware interrupts are enabled during the init, however,
they are not disabled during close.

Disable all hardware interrupts during close operation to avoid any
issues.

Fixes: 9e890103267e ("net/axgbe: add Rx/Tx setup")
