net: tsec: Re-arm packet buffer in error case
When an error is detected in the TSEC receive path, the driver currently
prints an error message, but leaves the corresponding packet descriptor
in its old state (i.e. owned by the CPU side). As a result, the packet
queue can be starved of available buffers if enough errors happen.
To recover from errors, re-arm the packet buffer descriptor after an
error has been detected.
Errors can be provoked by changing a PHY with phy-mode = "rgmii-id" to
phy-mode = "rgmii".
