Squashfs: reject negative file sizes in squashfs_read_inode()

In the Linux kernel, the following vulnerability has been resolved:

Squashfs: reject negative file sizes in squashfs_read_inode()

Syskaller reports a "WARNING in ovl_copy_up_file" in overlayfs.

This warning is ultimately caused because the underlying Squashfs file
system returns a file with a negative file size.

This commit checks for a negative file size and returns EINVAL.
