mount.cifs: set rc to 0 in libcap toggle_dac_capability

Thus spake Jochen:

The mount.cifs program from the cifs-utils package 5.5 did not work on
my Linux system. It just exited without an error message and did not
mount anything.

[...]

I think, when this variable rc is now used in this function, it has also
to be properly initialized there.
