Jon Mason f05b691150 iwlegacy: remove unnecessary read of PCI_CAP_ID_EXP 
The PCIE capability offset is saved during PCI bus walking.  It will
remove an unnecessary search in the PCI configuration space if this
value is referenced instead of reacquiring it.

* @fw_name_pre: Firmware filename prefix. The api version and extension
* (.ucode) will be added to filename before loading from disk. The

* @ucode_api_max: Highest version of uCode API supported by driver.
* @ucode_api_min: Lowest version of uCode API supported by driver.
* @scan_antennas: available antenna for scan operation
* @led_mode: 0=blinking, 1=On(RF On)/Off(RF Off)
*
* We enable the driver to be backward compatible wrt API version. The
* driver specifies which APIs it supports (with @ucode_api_max being the
* highest and @ucode_api_min the lowest). Firmware will only be loaded if
* it has a supported API version. The firmware's API version will be
* stored in @iwl_priv, enabling the driver to make runtime changes based
* on firmware version used.
*
* For example,
* if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
* Driver interacts with Firmware API version >= 2.
* } else {
* Driver interacts with Firmware API version 1.
* }
*
* The ideal usage of this infrastructure is to treat a new ucode API
* release as a new hardware revision. That is, through utilizing the
* iwl_hcmd_utils_ops etc. we accommodate different command structures
* and flows between hardware versions as well as their API
* versions.
