misc: vmw_vmci_defs: Mark 'struct vmci_handle VMCI_ANON_SRC_HANDLE' as __maybe_unused

vmw_vmci_defs.h is included by multiple source files. Some of which do not make use of 'struct vmci_handle VMCI_ANON_SRC_HANDLE' rendering it unused. Ensure the compiler knows that this is in fact intentional by marking it as __maybe_unused. This fixes the following W=1 warnings: In file included from drivers/misc/vmw_vmci/vmci_context.c:8: include/linux/vmw_vmci_defs.h:162:33: warning: ‘VMCI_ANON_SRC_HANDLE’ defined but not used [-Wunused-const-variable=] 162 | static const struct vmci_handle VMCI_ANON_SRC_HANDLE = { | ^~~~~~~~~~~~~~~~~~~~ In file included from drivers/misc/vmw_vmci/vmci_datagram.c:8: include/linux/vmw_vmci_defs.h:162:33: warning: ‘VMCI_ANON_SRC_HANDLE’ defined but not used [-Wunused-const-variable=] 162 | static const struct vmci_handle VMCI_ANON_SRC_HANDLE = { | ^~~~~~~~~~~~~~~~~~~~
