module/bdev_compress: Fix use logical block size in vbdev_compress_claim

Browse Source 
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.
