[PATCH 09/66] device/blkio.c: remove function

[Marin Ramesa]

Function block_io_mmap() is never a dev op, therefore it is 
unused and it can be written again easily if needed. I suggest
a removal of this function.

* device/blkio.c (block_io_mmap): Remove function.
* device/dev_pager.c (block_io_mmap): Remove forward declaration.
Remove the code in the case block_io_mmap() is an dev op.
