Subject: [PATCH v2 05/25] net/axgbe: disable interrupts during device removal

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")
