This patch removes the call of spdk_bdev_get_by_name() from
create_compress_bdev() by calling spdk_bdev_open_ext() and then passing
bdev descriptor to _prepare_for_load_init().
vbdev_init_reduce() returns the return code of spdk_bdev_open_ext()
directly if it is error to process the ENODEV case correctly.

Previously bdev was closed after reduce initialization and was re-opened
before bdev claim.
This patch series will fix the race condition due to the fact that
bdev pointer is valid only while bdev is opened.
Hence keeping bdev open from reduce initialization to bdev claim
is better.

Use logical block size instead of base bdev block size in
vbdev_compress_claim. This is relevant to enable the compress bdev to
present a logical block size that is different from the block size of
the base bdev (e.g. 512B logical on 4KB base bdev).
However, this is just an internal fix/preparation and there is
currently not yet a way for users to specify a different
logical block size, e.g. through an rpc.py parameter.
