[PATCH v1 1/1] SecurityPkg/Tcg2Smm: Initialize local Status variable

["Michael Kubacki" <mikuback@linux.microsoft.com>]

From: Michael Kubacki <michael.kubacki@microsoft.com>

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3277

Initializes the Status variable in TcgMmReadyToLock().

Fixes a Clang build failure:
Tcg2Smm.c - SecurityPkg\Tcg\Tcg2Smm\Tcg2Smm.c:254:7: error:
variable 'Status' is used uninitialized whenever 'if'
condition is false [-Werror,-Wsometimes-uninitialized]
