wifi: iwlwifi: mvm: Fix bit size calculation in iwl_dbgfs_tas_get_status_read

Corrected the bit size calculation in the for_each_set_bit macro in
the iwl_dbgfs_tas_get_status_read(). The previous implementation used
sizeof(dyn_status), which only accounts for the number of bytes.
This has been updated to TAS_DYNA_STATUS_MAX to ensure the loop iterates
over the correct number of valid bits in dyn_status.
