staging: r8188eu: Hal_MappingOutPipe should return an int

Browse source

Update the Hal_MappingOutPipe function to return 0 for success or -EXNIO
if the caller requested more than the number of available endpoints.
This error code is also used by usb_find_common_endpoints if a requested
endpoint was not found.

Unlike a boolean return value, a negative error code can be returned to
external functions that call the r8188eu driver, e.g. to the caller of our
probe function.

HalUsbSetQueuePipeMapping8188EUsb passes the return value of
Hal_MappingOutPipe on to its caller. We have to change its return type
from bool to int as well.
