linux_wlan.c and wilc_wlan.c was separated into two part at the beginning to support various platforms. They are in charge of send/receive control and packet data, so they will be merged into one file wlan.c later. First of all, wilc_wlan_dev_t which is used as global variable of wilc_wlan.c will be moved into struct wilc. This patch moves all members of wilc_wlan_dev_t to struct wilc and use wilc instead of g_wlan. Finally remove wilc_wlan_dev_t and g_wlan.
