The functions are almost identical, so factor the common code into new
function wilc_wlan_cfg_apply_wid(). No functional change.

+ * wilc_wlan_cfg_apply_wid() - Add a config set or get (query).
+ * @vif: The virtual interface to which the set/get applies.

+ * 0 otherwise.
+ * @wid: The WID to use.
+ * @buffer: For a set, the bytes to include in the request,
+ * for a get, the buffer in which to return the result.
+ * @buffer_size: The size of the buffer in bytes.
+ * @commit: Should be 1 if the config packet should be sent after
+ * adding this request/query.
+ * @drv_handler: An opaque cookie that will be sent in the config header.
+ * @set: Should be true if a set, false for get.
+ *
+ * Add a WID set/query to the current config packet and optionally
+ * submit the resulting packet to the chip and wait for its reply.
+ *
+ * Return: Zero on failure, positive number on success.
