bdev: Add spdk_bdev_io_get_io_channel API



Currently struct bdev_io holds io_channel that the I/O was submitted
on through bdev_io::bdev_channel, but bdev_io::bdev_channel is private
in bdev.c and cannot be referenced in other files.

Hence add an new API spdk_bdev_io_get_io_channel API to get io_channel
coniveniently.
