Do wal_level and hot standby checks when doing crash-then-archive recovery.

hlinnaka · hlinnaka · commit e7ec05562ed7 · 2014-03-05T14:45:55.000+02:00
CheckRequiredParameterValues() should perform the checks if archive recovery
was requested, even if we are going to perform crash recovery first.

Reported by Kyotaro HORIGUCHI. Backpatch to 9.2, like the crash-then-archive
recovery mode.
