Reset scan state when opening a new file

When we opened a new file after encountering a parse error, we weren't
resetting our scan state, and continued to read out of the old buffer
rather than that of the new file.

Fixes a regression introduced in 9887842e ('Use fread() instead of
getc()').

Test case:
    xkbcomp -lfhlpR "path/to/xkeyboard-config.git/symbols/*"
The Makefiles in that tree would cause parse errors, the resulting directory
file is incomplete (down from ~12000 to ~230 lines).
