Assert only valid flag bits are passed to visibilitymap_set()

If visibilitymap_set() is called with flags containing a higher bit thanVISIBILITYMAP_ALL_FROZEN, the state of neighboring pages is affected. Whilethere was an assertion that *some* valid bits were set, it did not checkthat *only* valid bits were. Change that.Discussion:https://postgr.es/m/20230331043300.gux3s5wzrapqi4oe@awork3.anarazel.de
