cifs: Mangle string used for unc in /proc/mounts

Browse source

The string for "unc=" in /proc/mounts needs to be escaped. The current
behaviour can create problems in cases when mounting a share starting
with a number.

example:
>mount -t cifs -o username=test,password=x vm140-31:/17000-test /mnt
>mount -o remount,password=x /mnt
mount error: could not resolve address for vm140-31x00-test: Unknown
error

The sub-string "\170" which is part of the unc for the mount above in
/proc/mounts is interpreted as character'x' in the case above. Escaping
the string fixes the problem.
