usb: typec: tipd: Remove WARN_ON in tps6598x_block_read

mainline inclusion
from mainline-v5.16-rc1
commit b7a0a63f
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9HOEF
CVE: CVE-2021-47210

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b7a0a63f3fed57d413bb857de164ea9c3984bc4e



--------------------------------

Calling tps6598x_block_read with a higher than allowed len can be
handled by just returning an error. There's no need to crash systems
with panic-on-warn enabled.
