The table rs_ht_to_legacy is used to get the next legacy rate following the last HT or VHT rate in the LQ rates table. The mapping wasn't correct as well as didn't include entries for MCS8/9 which led to out of bounds access. This didn't trigger a crash but led to legacy rate entries using 1Mbps rate. In 5Ghz this probably caused the Tx to fail completely given that Tx attempt would have reached the legacy entries and 1Mbps isn't valid.

Introduce rs_rate which represents a rate. Use this structure instead of iwl_scale_tbl_info where we're dealing with a single rate. This avoids allocating the big iwl_scale_tbl_info structure on the stack in several cases like converting to ucode rate format or from ucode rate format.

Expected TPT table was updated only when switching to a new modulation. This is wrong as toggling aggregation changes the expected TPT signficantly. This leads to scenarios where turning aggregation on after being in MIMO sends us back to SISO despite a perfect success ratio. This occurred because the TPT of the SISO mode was being estimated based on aggregation while the MIMO one wasn't. Also remove an error print which isn't an error anymore since we might be updating the expected TPT table due to aggregation changes.

Switch to using the new btcoex decision api regarding MIMO and stop accessing the internal btcoex structs. In case MIMO should be disabled it would detect this upon the next Tx and force a search.
