[PATCH] block/floppy: fix section mismatch warnings

In latest -mm a number of section mismatch warnings are generated for
floppy.o like the following:

WARNING: drivers/block/floppy.o - Section mismatch: reference to    \
.init.data: from .text between 'init_module' (at offset 0x6976) and \
'cleanup_module'

The warning are caused by a reference to floppy_init() which is __init from
init_module() which is not declared __init.  Declaring init_module() _init
fixes this.
