In SimpleLruReadPage_ReadOnly, we first try to find the SLRU page in
shared buffer under shared lock, then conditionally visit
SimpleLruReadPage if reading is necessary. IMHO, we should update
hit_count if we can find the buffer in SimpleLruReadPage_ReadOnly
directly. Am I missing something?

Attached a patch for the same.
