scsi: ufs: core: Revert "Make HID attributes visible"

[ Upstream commit f838d624fd1183e07db86f3138bcd05fd7630a1e ]

Patch "Make HID attributes visible" is needed for older kernel versions
(e.g. 6.12) where ufs_get_device_desc() is called from ufshcd_probe_hba().
In these older kernel versions ufshcd_get_device_desc() may be called
after the sysfs attributes have been added. In the upstream kernel however
ufshcd_get_device_desc() is called before ufs_sysfs_add_nodes(). See also
the ufshcd_device_params_init() call from ufshcd_init(). Hence, calling
sysfs_update_group() is not necessary.

See also commit 69f5eb78d4b0 ("scsi: ufs: core: Move the
ufshcd_device_init(hba, true) call") in kernel v6.13.

This patch fixes the following kernel warning:
