[PATCH 1/1] net/sfc: add missing error code indication to MAE init path

[Ivan Malov]

A failure to allocate a bounce buffer for encap. header
parsing results in falling to the error path but does
not set an appropriate error code. Fix this.

Fixes: 1bbd1ec2348a ("net/sfc: support action VXLAN encap in MAE backend")
