SecurityPkg: also clear HashInterfaceHob.SupportedHashMask

Commit 4cc2b63bd829426b05bad0d8952f1855a10d6ed7 fixed an out of bounds
ZeroMem() call. However, as Laszlo Ersek pointed out, the intent was
to clear all but the Identifier (to revert the effect of
RegisterHashInterfaceLib()). For that, it should clear the
SupportedHashMask too.
