crypto/threads_win.c: type casted destination of InterlockedExchange{,64} calls

Explicitly cast dst argument of InterlockedExchange{,64} calls
in CRYPTO_atomic_store{,_int}() to LONG{64,} volatile *, respectively,
to work around incompatible pointer type errors on 64-bit MinGW builds.

Initially Reported by Splediferous.
