[linux-lvm] lvm fails when /proc/devices contains "-1 smblk"

[John Mesmon]

It filters out all the possible devices, resulting in almost all
operations failing (maybe all, I haven't checked that far).

Introduced by c929a0b3c8c1cd4a32458b5db0aa3d221a949aad

My opinion is that there is no need for the check that commit adds, It
can only break things (when the range of valid block devices changes).

For reference, the relavent portion of my /proc/devices:

Character devices:
  1 mem
  4 /dev/vc/0
  4 tty
...
251 macvtap
252 kcopy
253 bsg
254 rtc

Block devices:
 -1 smblk
  1 ramdisk
256 rfd
257 ssfdc
259 blkext
  7 loop
...
