[PATCH 5.15 359/846] tpm_tis: Fix an error handling path in tpm_tis_core_init()

[Greg Kroah-Hartman]

From: Christophe Jaillet <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit e96d52822f5ac0a25de78f95cd23421bcbc93584 ]

Commit 79ca6f74dae0 ("tpm: fix Atmel TPM crash caused by too frequent
queries") has moved some code around without updating the error handling
path.

This is now pointless to 'goto out_err' when neither 'clk_enable()' nor
'ioremap()' have been called yet.

Make a direct return instead to avoid undoing things that have not been
done.
