Cast negative debugfs values to u64
Since
commit 488dac0c9237647e9b8f788b6a342595bfa40bda

libfs: fix error cast of negative value in simple_attr_write()
the kernel now rejects any negative values written to debugfs, rather
than casting them to u64. Since we are accustomed to having the -1 mean
U64_MAX, perform that conversion ourselves.
