Alexander Egorenkov 455ad953a9 zdump: Fix /dev/mem reading ...

This commit makes zgetdump work with /dev/mem again.
zg_seek() should not attempt to verify the given offset for devices before
issuing lseek() because special devices like /dev/mem report 0 in
stat.sb_size.

$ zgetdump -i /dev/mem
zgetdump: Trying to seek past file end "/dev/mem"

Fixes: 11e78cada5 ("zdump: catch attempts to seek past end of file in zg_seek()")
