comdlg32: Add a break statement to mark a semantic separtation

[Andrew Talbot]

Changelog:
    comdlg32: Add a break statement to mark a semantic separtation.

Although this break statement would be technically redundant, it helps to delineate betweeen a shared do-something code path and a separate shared do-nothing code path. The existing fall-through works only because the second code path happens to be a NOP.
