In fact inode_get_rsv_space() function is special in comparison with inode_{add,sub,claim}_rsv_space() functions, because it may return correct result even for fs without reserved space support(correct val == 0). Add trivial check for that case. The patch fix regression(BUG at fs/quota/dquot.c:1350) introduced in following commit: fd8fbfc1709822bd94247c5b2ab15a5f5041e103
