[PATCH v3 6/7] staging: r8188eu: IntArray and C2hArray are set but never used

[Michael Straube <straube.linux@gmail.com>]

The fields IntArray and C2hArray of struct hal_data_8188e are set but
never used. Remove them and remove interrupt_handler_8188eu() since it
does nothing now.

While at it, remove the unsed defines USB_INTR_CONTENT_CPWM1_OFFSET
and USB_INTR_CONTENT_CPWM2_OFFSET as well.

v3: Remove INTERRUPT_MSG_FORMAT_LEN from rtl8188e_recv.h.
v2: Remove interrupt_handler_8188eu() since it does nothing now.
