kdump: fix save vmcore path for fadump 

With fadump support, dracut-kdump.sh script is installed into default
initrd to capture vmcore generated by firmware assisted dump. Thus in
fadump case, the same initrd is being used for normal boot as well as
boot after system crash. Hence a device node, added by firmware while
system crashes, is checked to identify if it is a normal boot or boot
after crash to determine whether or not capture vmcore. While testing
fadump in  fedora21 alpha, observed that  vmcore capture is initiated
even during normal boot, inspite of this check, with the below error:

    "kdump.sh[451]: /bin/kdump.sh: line 5: return: can only `return'
     from a function or sourced script"

The below patch tries to fix this issue.
