fs/libfs.c: fix simple_attr_write() on 32bit machines
Assume that /sys/kernel/debug/dummy64 is debugfs file created by
debugfs_create_x64().
# cd /sys/kernel/debug
# echo 0x1234567812345678 > dummy64
# cat dummy64
0x0000000012345678
# echo 0x80000000 > dummy64
# cat dummy64
0xffffffff80000000
A value larger than INT_MAX cannot be written to the debugfs file created
by debugfs_create_u64 or debugfs_create_x64 on 32bit machine. Because
simple_attr_write() uses simple_strtol() for the conversion.
To fix this, use simple_strtoll() instead.
