[PATCH 06/10] iwl3945: use iwl3945_tx_cmd instead of iwl_tx_cmd

[Zhu Yi <yi.zhu@intel.com>]

From: Winkler, Tomas <tomas.winkler@intel.com>

The patch replaces iwl_tx_cmd with iwl3945_tx_cmd to complete
transitions introduced by commit
77cb4db173d72d1a8c6c89015784a815bfd85221 "iwlwifi: use iwl_cmd instead
of iwl3945_cmd"
