[ Upstream commit d25ed413d5e51644e18f66e34eec049f17a7abcb ]
When debugging an issue I found implausible values in state->pause. Reason in that state->pause isn't initialized and later only single bits are changed. Also the struct itself isn't initialized in phylink_resolve(). So better initialize state->pause and other not yet initialized fields.
v2: - use right function name in subject v3: - initialize additional fields
