[PATCH] lib/lzo/lzo1x_compress.c: replace ternary operator with min() and min_t()

[Jiangshan Yi]

From: Jiangshan Yi <yijiangshan@xxxxxxxxxx>

Fix the following coccicheck warning:

lib/lzo/lzo1x_compress.c:54: WARNING opportunity for min().
lib/lzo/lzo1x_compress.c:329: 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.
