[PATCH v2] fs: exfat: improve error code handling in exfat_find_empty_entry()

[Haotian Zhang]

Change the type of 'ret' from unsigned int to int in
exfat_find_empty_entry(). Although the implicit type conversion
(int -> unsigned int -> int) does not cause actual bugs in
practice, using int directly is more appropriate for storing
error codes returned by exfat_alloc_cluster().

This improves code clarity and consistency with standard error
handling practices.
