[PATCH v2 4/7] FmpDevicePkg/FmpDependencyCheckLib: Return unsatisfied on handle failure

["Michael Kubacki" <michael.kubacki@outlook.com>]

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

CheckFmpDependency () will currently return that dependencies are
satisfied if the initial call in the function to locate handles
that have gEfiFirmwareManagementProtocolGuid installed fails.

This change updates the error handling to return FALSE (dependencies
are not satisfied) if this handle search fails.
