[PATCH -next] efi/arm64: return zero from ptdump_init()

[Qian Cai]

The commit e2a2e56e4082 ("arm64: dump: no need to check return value of
debugfs_create functions") converted ptdump_debugfs_register() from
void, but forgot to fix the efi version of ptdump_init().

drivers/firmware/efi/arm-runtime.c: In function 'ptdump_init':
drivers/firmware/efi/arm-runtime.c:52:9: error: void value not ignored as it 
ought to be
   52 |  return ptdump_debugfs_register(&efi_ptdump_info, "efi_page_tables");
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/firmware/efi/arm-runtime.c:53:1: warning: control reaches end of 
non-void function [-Wreturn-type]

Fixes: e2a2e56e4082 ("arm64: dump: no need to check return value of 
debugfs_create functions")
