[PATCH 04/12] staging: rtl8188eu: remove unused hal_data_8188e members

[Ivan Safonov]

u8 *pfirmware and u32 fwsize of hal_data_8188e structure not used.

The pfwdata variable used to store a pointer to the buffer
in rtl88eu_download_fw and the pfwbody variable points to the body
of the firmware (without header).
