ext4: make variable "count" signed
stable inclusion from stable-4.19.249 commit c86fce1d8c083d268103d2d19e5a9a66000a8e6f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5I4FP CVE: NA -------------------------------- commit bc75a6eb856cb1507fa907bf6c1eda91b3fef52f upstream. Since dx_make_map() may return -EFSCORRUPTED now, so change "count" to be a signed integer so we can correctly check for an error code returned by dx_make_map().
