From: Jiangshan Yi <yijiangshan@xxxxxxxxxx>
Fix the following coccicheck warning:
fs/reiserfs/prints.c:459: WARNING opportunity for min().
fs/reiserfs/resize.c:100: WARNING opportunity for min().
fs/reiserfs/super.c:2508: WARNING opportunity for min().
fs/reiserfs/super.c:2557: WARNING opportunity for min().
min() and min_t() macro is defined in include/linux/minmax.h.
It avoids multiple evaluations of the arguments when non-constant and
performs strict type-checking.
