fuse: Pass correct lend value to filemap_write_and_wait_range()
commit e388164ea385f04666c4633f5dc4f951fca71890 upstream.
The acceptable maximum value of lend parameter in
filemap_write_and_wait_range() is LLONG_MAX rather than -1. And there is
also some logic depending on LLONG_MAX check in write_cache_pages(). So
let's pass LLONG_MAX to filemap_write_and_wait_range() in
fuse_writeback_range() instead.
Fixes: 59bda8ecee2f ("fuse: flush extending writes")
