commit 37b4599547e324589e011c20f74b021d6d25cb7f upstream.
Clang static analysis reports this problem
ioctl.c:3333:8: warning: 3rd function call argument is an
uninitialized value
ret = exclop_start_or_cancel_reloc(fs_info,
cancel is only set in one branch of an if-check and is always used. So
initialize to false.
