dm-cache: remove pointless error check
Smatch reported following:
'''
drivers/md/dm-cache-target.c:3204 parse_cblock_range() warn: sscanf doesn't return error codes
drivers/md/dm-cache-target.c:3217 parse_cblock_range() warn: sscanf doesn't return error codes
'''
Sscanf doesn't return negative values at all.
