CVE-2025-68350

exfat: fix divide-by-zero in exfat_allocate_bitmap

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

exfat: fix divide-by-zero in exfat_allocate_bitmap

The variable max_ra_count can be 0 in exfat_allocate_bitmap(),
which causes a divide-by-zero error in the subsequent modulo operation
(i % max_ra_count), leading to a system crash.
When max_ra_count is 0, it means that readahead is not used. This patch
load the bitmap without readahead.
