[sfnt] Fix memory leak in png loading. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=1182552 Memory is allocated and the pointer assigned to `rows` inside a 'setjmp' scope. This memory must be freed outside the 'setjmp' scope after a 'longjmp'. Since `rows` is a local and modified inside the 'setjmp' scope it must be marked volatile or it will have an indeterminate value after the 'longjmp'. * src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak of `rows`.
