[Qemu-devel] [PATCH] block: fix a warning and possible truncation

[Blue Swirl]

Fix a warning from OpenBSD gcc (3.3.5 (propolice)):
/src/qemu/block.c: In function `bdrv_info_stats_bs':
/src/qemu/block.c:1548: warning: long long int format, long unsigned
int arg (arg 6)

There may be also truncation effects.

Alternatively 'ULL' prefix could be appended to BDRV_SECTOR_SIZE
definition but that may have other side effects.
