devlink: Always use user_ptr[0] for devlink and simplify post_doit

Browse Source 
Currently devlink instance is searched on all doit() operations.
But it is optionally stored into user_ptr[0]. This requires
rediscovering devlink again doing post_doit().

Few devlink commands related to port shared buffers needs 3 pointers
(devlink, devlink_port, and devlink_sb) while executing doit commands.
Though devlink pointer can be derived from the devlink_port during
post_doit() operation when doit() callback has acquired devlink
instance lock, relying on such scheme to access devlik pointer makes
code very fragile.

Hence, to avoid ambiguity in post_doit() and to avoid searching
devlink instance again, simplify code by always storing devlink
instance in user_ptr[0] and derive devlink_sb pointer in their
respective callback routines.
