[PATCH] fuse: clean up request size limit checking
Change the way a too large request is handled. Until now in this case the
device read returned -EINVAL and the operation returned -EIO.
Make it more flexibible by not returning -EINVAL from the read, but restarting
it instead.
Also remove the fixed limit on setxattr data and let the filesystem provide as
large a read buffer as it needs to handle the extended attribute data.
The symbolic link length is already checked by VFS to be less than PATH_MAX,
so the extra check against FUSE_SYMLINK_MAX is not needed.
The check in fuse_create_open() against FUSE_NAME_MAX is not needed, since the
dentry has already been looked up, and hence the name already checked.
