SecurityPkg/FvReportPei: remove redundant sizeof

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3333

In function InstallPreHashFvPpi, when calculating the size
of struct HASH_INFO, sizeof is used twice. This bug does
not lead to buffer overflow, "sizeof (HASH_INFO)" is 4,
whereas "sizeof (sizeof (HASH_INFO))" is 4 or 8.
