block/blkio: Set BlockDriver::has_variable_length to false
Setting it to true can cause the device size to be queried from libblkio
in otherwise fast paths, degrading performance. Set it to false and
require users to refresh the device size explicitly instead.
Fixes: 4c8f4fda0504 ("block/blkio: Tolerate device size changes")
