    schannel: fix -Wsign-compare warning
    
    MinGW warns:
    /lib/vtls/schannel.c:219:64: warning: signed and unsigned type in
    conditional expression [-Wsign-compare]
    
    Fix this by casting the ptrdiff_t to size_t as we know it's positive.
    
    Closes https://github.com/curl/curl/pull/2721
