tpm: st33zp24: Fix missing cleanup on get_burstcount() error

Browse source

[ Upstream commit 3e91b44c93 ]

get_burstcount() can return -EBUSY on timeout. When this happens,
st33zp24_send() returns directly without releasing the locality
acquired earlier.

Use goto out_err to ensure proper cleanup when get_burstcount() fails.
