autofs-5.0.9 - revert special case cifs escapes

From: Ian Kent <ikent@redhat.com>

The patch this reverts added an additional dquote on the mount location
to revolve "\"s but this causes inconsistent quoting between the lookup
key and the mount location when it is substituted using the &.

As described in the original patch:
"Since "\" is a valid seperator for cifs shares it can't be used to escape
characters in the share name passed to mount.cifs. So we have no choice
but to require that the seperator we use is "/" and de-quote the string
before sending it to mount.cifs."

We do need to require that the seperator "/" is used which alone should
eliminate the need for an additional dequote and expect that invalid
share name mounts will fail.
