Fix delete/free mismatch in QtXmlPatterns

Fixes valgrind warning like this:
Mismatched free() / delete / delete []
  at: operator delete(void*) (vg_replace_malloc.c:387)
  by: QPatternist::Decimal::toString(double) (qdecimal.cpp:121)

Reason for the warning is that toString above calls qdtoa the result of
which should be released with free(), not delete.
