[svn-r13575] Problem:

dsets failed on kelgia with assertion failure in H5Ocache.c. Kelgia
	could not deal with the comparison of uint64_t variable with 4294967296 constant.
	
Solution:
	By John's suggestions used suffix LL for the constant.

Platforms tested:
	kelgia, kagiso, and smirom with icc compiler
