ASoC: fsl: Fix refcount leak in imx_sgtl5000_probe

stable inclusion
from stable-v5.10.121
commit e84aaf23ca82753d765bf84d05295d9d9c5fed29
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6CQ

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e84aaf23ca82753d765bf84d05295d9d9c5fed29

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

[ Upstream commit 41cd312d ]

of_find_i2c_device_by_node() takes a reference,
In error paths, we should call put_device() to drop
the reference to aviod refount leak.
