nvrl bca22056b0 fix(fuse): report write errors at close, and take fsync and fallocate as POSIX does
flush answered ok at once and release synced the scratch file, but close(2)
only returns what flush answers, so a full disk at close was reported to
nobody. flush now syncs a handle with writes on a worker and returns ENOSPC,
EDQUOT or EIO; release then finds the pages on disk instead of writing a
whole file back on the dispatch loop. fsync on a descriptor opened for
reading no longer fails with EBADF (B222).

fallocate passed any mode through and tracked only a punched hole or
growth: a zeroed range came back from the remote base at commit, and a
collapse or insert corrupted the file. Unsupported modes now get EOPNOTSUPP,
zeroed ranges count as written, the real errno is returned, and the state
lock is not held across the syscall (B224).
