Fix f2fs_report_zone()
The definition of struct blk_zone_report is as follows:
struct blk_zone_report {
__u64 sector;
__u32 nr_zones;
__u32 flags;
struct blk_zone zones[0];
};
Since f2fs_report_zone() allocates the above data structure with
malloc() and since f2fs_report_zone() only initializes the sector and
nr_zones members, the flags member is not initialized. Modify
f2fs_report_zone() such that 0 is passed as flags to the
BLKREPORTZONE ioctl instead of a random value. This has been
discovered by reading the source code.
