struct enum_csc_policy isn't terminated

[Yasuma Takeda]

In Samba-JP, a following problem was reported.

Since the "enum_csc_policy" struct doesn't terminate appropriately,
it may occur buffer overflow. 

I confirmed this problem using by SWAT.
The "csc policy" entry includes "enum_map_to_guest" struct entry.

This problem exists in 2.2.4 and HEAD.
Please fix.
