ovl: fix lseek overflow on 32bit
[ Upstream commit a4ac9d45c0cd14a2adc872186431c79804b77dbf ]
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.
