erofs: silence uninitialized variable warning in z_erofs_scan_folio()
Smatch complains that: fs/erofs/zdata.c:1047 z_erofs_scan_folio() error: uninitialized symbol 'err'. The issue is if we hit this (!(map->m_flags & EROFS_MAP_MAPPED)) { condition then "err" isn't set. It's inside a loop so we would have to hit that condition on every iteration. Initialize "err" to zero to solve this.
