Subject: [PATCH 5.16 094/227] iwlwifi: mvm: fix condition which checks the version of rate_n_flags

From: Miri Korenblit <miriam.rachel.korenblit@...el.com>

commit be8287c9b8326d767429c8371bbc78b33f6efe13 upstream.

We're checking the FW version of TX_CMD in order to decide whether to
convert rate_n_flags from the old format to the new one.  If the API
is smaller or equal to 6 we should convert it.  Currently we're
converting if the API version is greater than 6. Fix it.
