(Staker only) Removes a validator from the pool, deactivating its stake.

Only succeeds if the validator stake account has the minimum of max(crate::MINIMUM_ACTIVE_STAKE, solana_program::stake::tools::get_minimum_delegation()) plus the rent-exempt amount.

Keys:

• stakePoolAddress [w] - Stake pool.
• staker [s] Staker.
• withdrawAuthority [] Stake pool withdraw authority.
• validatorList [w] Validator stake list storage account.
• stakeAccount [w] Stake account to remove from the pool.
• transientStakeAccount [] Transient stake account, to check that that we're not trying to activate.
