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