libsepol/cil: Move initialization of bitmap in __cil_permx_to_bitmap()

Nicolas Iooss reports:
  When __cil_permx_to_bitmap() calls __cil_permx_str_to_int() on an
  invalid number, local variablt "bitmap" is left initialized when
  the function returns and its memory is leaked.

  This memory leak has been found by running clang's Address Sanitizer
  on a set of policies generated by American Fuzzy Lop.

Move the initialization of bitmap to right before ebitmap_set_bit()
and after the call to __cil_permx_str_to_int().
