[PATCH 095/379][SRU][OEM-5.6] bus: mhi: core: Fix a NULL vs IS_ERR check in mhi_create_devices()

[You-Sheng Yang]

From: Dan Carpenter <dan.carpenter at oracle.com>

BugLink: https://bugs.launchpad.net/bugs/1879633

The mhi_alloc_device() function never returns NULL, it returns error
pointers.

Fixes: da1c4f856924 ("bus: mhi: core: Add support for creating and destroying MHI devices")
