net: stmmac: Fix unused values warnings

Browse source 
The commit 8532f613bc ("net: stmmac: introduce MSI Interrupt routines
for mac, safety, RX & TX") introduced the converity warnings:-

  1. Unused value (UNUSED_VALUE)
     assigned_value: Assigning value REQ_IRQ_ERR_MAC to irq_err here,
     but that stored value is not used.

  2. Unused value (UNUSED_VALUE)
     assigned_value: Assigning value REQ_IRQ_ERR_NO to irq_err here,
     but that stored value is overwritten before it can used.

  3. Unused value (UNUSED_VALUE)
     assigned_value: Assigning value REQ_IRQ_ERR_WOL to irq_err here,
     but that stored value is not used.

Fixed these by removing the unnecessary value assignments.
