[PATCH v3 5/9] net: liteeth: do not set len to 0 before printing it

[Sascha Hauer <s.hauer@pengutronix.de>]

'len' is set to 0 before it is printed, so printing it doesn't give any
information. Drop this and print the erroneous len instead. Also, do not
initialize 'len' initially as this initialization value is never used.
