staging: exfat: fix uninitialized variable ret



Currently there are error return paths in ffsReadFile that
exit via lable err_out that return and uninitialized error
return in variable ret. Fix this by initializing ret to zero.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: c48c9f7f ("staging: exfat: add exfat filesystem code to staging")
