Miklos Szeredi ac157dd149 ovl: fix lseek overflow on 32bit 
commit a4ac9d45c0 upstream.

ovl_lseek() is using ssize_t to return the value from vfs_llseek().  On a
32-bit kernel ssize_t is a 32-bit signed int, which overflows above 2 GB.

Assign the return value of vfs_llseek() to loff_t to fix this.
