fuse: validate outarg offset and size in notify store/retrieve
Add validation checking for outarg offset and outarg size values passed
in by the server. MAX_LFS_FILESIZE is the maximum file size supported.
The fuse_notify_store_out and fuse_notify_retrieve_out structs take in
a uint64_t offset.
Add logic to ensure:
* outarg.offset is less than MAX_LFS_FILESIZE
* outarg.offset + outarg.size cannot exceed MAX_LFS_FILESIZE
* potential uint64_t overflow is fixed when adding outarg.offset and
outarg.size.
