mlxsw: Fix some IS_ERR() vs NULL bugs
[ Upstream commit c391eb8366ae052d571bb2841f1ccb4d39f3ceb8 ]
The mlxsw_sp_acl_rulei_create() function is supposed to return an error
pointer from mlxsw_afa_block_create(). The problem is that these
functions both return NULL instead of error pointers. Half the callers
expect NULL and half expect error pointers so it could lead to a NULL
dereference on failure.
This patch changes both of them to return error pointers and changes all
the callers which checked for NULL to check for IS_ERR() instead.
Fixes: 4cda7d8d7098 ("mlxsw: core: Introduce flexible actions support")
