bdev/raid: check whether supports FLUSH/RESET

Browse Source 
io_types like FLUSH and RESET are not always supported
by base bdev modules. For example: virtio_blk bdev doesn't
support FLUSH; ocf or ftl vbdev doesn't support RESET.

* brief:
* raid_bdev_io_type_unmap_supported is check whether unmap is supported in
* raid bdev module. If anyone among the base_bdevs doesn't support, the
* raid device doesn't supports. For the base_bdev which is not discovered, by default
* it is thought supported.
* _raid_bdev_io_type_supported checks whether io_type is supported in

*
* params:
* raid_bdev - pointer to raid bdev context
* io_type - io type
* returns:
* true - io_type is supported
* false - io_type is not supported
