disk: fix blk_get_device_part_str()
blk_get_device_part_str() should always initialize all info fields
including sys_ind. As a side effect the code is simplified.
Replace '(0 ==' by '(!' to conform with Linux coding style.
Fixes: 4d907025d6a5 ("sandbox: restore ability to access host fs through standard commands")
