The EFA driver is written with success oriented flows in mind, meaning
that functions should mostly end with a return 0 statement.
Error flows return their error value on their own instead of assuming
that the function will return the error at the end.
This commit fixes a bunch of functions that were not aligned with this
behavior.

This more closely follows how other subsytems work, with owner being a
member of the structure containing the function pointers.

No reason for every driver to emit code to set this, just make it part of
the driver's existing static const ops structure.
