Add a lock to protect the critical region in Service APIs for gEfiBlockIoProtocolGuid and gEfiSimpleFileSystemProtocolGuid Protocol to prevent re-entrance of the same API from from different TPL level. In UEFI 2.1 spec, it is state that the service API for this Protocol is callable at EFI_TPL_CALLBACK level.
