Avoid a memory leak when allocation of a pCAL buffer fails

Set the PNG_FREE_PCAL flag immediately after the allocation of the
first pCAL buffer, so that, if any one of the subsequent allocations
fail, all pCAL buffers still get deallocated by png_free_data.

Also reorder the initialization of other PNG_FREE_ flags (without
altering the semantics) to improve the overall consistency inside
the pngset.c module.
