[PATCH] scsi: ufs: core: Initialize hba->rpmbs list in ufshcd

[Ao Sun <ao.sun@transsion.com>]

From: Ao Sun <ao.sun@transsion.com>

Initialize the hba->rpmbs list in ufshcd_alloc_host() to prevent NULL
pointer dereference in the device teardown path if ufs_rpmb_probe()
fails.

Fixes: b06b8c421485 ("scsi: ufs: core: Add OP-TEE based RPMB driver for UFS devices")
