net: macb: Fix tx_ptr_lock locking
macb_start_xmit and macb_tx_poll can be called with bottom-halves
disabled (e.g. from softirq) as well as with interrupts disabled (with
netpoll). Because of this, all other functions taking tx_ptr_lock must
use spin_lock_irqsave.
Fixes: 138badbc21a0 ("net: macb: use NAPI for TX completion path")
