Subject: block: remove mount target file if it's a link
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d1f1f2b38fa1e7b594bd005e563679a40e4d7e95;p=project%2Ffstools.git

block: remove mount target file if it's a link

Links like that can remain from using autofs and can cause mounting
errors after switching to non-autofs:

block: mounting /dev/sda1 (vfat) as /mnt/sda1 failed (2) - No such file or directory
