[ Upstream commit fa05bdb89b ]
This reverts commit 9ea3e52c5b.
Cited commit added a check to make sure 'action' is not NULL, but
'action' is already dereferenced before the check, when calling
flow_offload_has_one_action().
Therefore, the check does not make any sense and results in a smatch
warning:
include/net/flow_offload.h:322 flow_action_mixed_hw_stats_check() warn:
variable dereferenced before check 'action' (see line 319)
Fix by reverting this commit.
