Peter Rajnoha 55c13f3de4 dev-cache: fix use of uninitialized device status if reading outdated .cache record
As part of fix that came with cf700151eba483aeedbf790fd66ce1c44e19c707,
I forgot to add the check whether the result of stat was successful or
not. This bug caused uninitialized buffer to be used for entries
from .cache file which are no longer valid.

This bug may have caused these uninitialized values to be used further,
for example (see the unreal (2567,590944) representing major:minor
pair):

$ pvs
  /dev/abc: stat failed: No such file or directory
  Path /dev/abc no longer valid for device(2567,590944)
  PV               VG   Fmt  Attr PSize   PFree
  /dev/mapper/test      lvm2 ---  104.00m 104.00m
  /dev/vda2        rhel lvm2 a--    9.51g      0
