esp: Fix error handling on layer 2 xmit.
esp_output_tail() and esp6_output_tail() can return negative
and positive error values. We currently treat only negative
values as errors, fix this to treat both cases as error.
Fixes: fca11ebde3f0 ("esp4: Reorganize esp_output")
Fixes: 383d0350f2cc ("esp6: Reorganize esp_output")
