tpm: tpm_crb: relinquish locality on error path.

[ Upstream commit 1fbad3028664e114d210dc65d768947a3a553eaa ]

In crb_map_io() function, __crb_request_locality() is called prior
to crb_cmd_ready(), but if one of the consecutive function fails
the flow bails out instead of trying to relinquish locality.
This patch adds goto jump to __crb_relinquish_locality() on the error path.

Fixes: 888d867df441 (tpm: cmd_ready command can be issued only after granting locality)
