octeontx2-pf: Error handling support
HW reports many errors on the receive and transmit paths.
Such as incorrect queue configuration, pkt transmission errors,
LMTST instruction errors, transmit queue full etc. These are reported
via QINT interrupt. Most of the errors are fatal and needs
reinitialization.
Also added support to allocate receive buffers in non-atomic context
when allocation fails in NAPI context.
