avfilter/vf_vpp_qsv: Don't overrun stack array

8b83dad82512a6948b63408f964463b063ad24c9 added another potentially used
video enhancement filter without increasing a define for the number of
such options which is used as the size of stack array. This can lead to
a buffer overrun if all filters are used simultaneously. So increase
said number.

Fixes Coverity ticket #1489775.
