Shuhei Matsumoto f057ffbaff bdev/passthru: Open base bdev first using spdk_bdev_open_ext() 
vbdev_passthru_register() gets bdev name instead of bdev pointer
as a parameter, and open the corresponding base bdev first using
spdk_bdev_open_ext().

The purpose is to fix the race condition due to the time gap
between spdk_bdev_get_by_name() and spdk_bdev_open(). A bdev pointer
is valid only while the bdev is opened.

Resize event is not supported for now.
