[PATCH 5.19 0527/1157] Bluetooth: hci_intel: Add check for platform_driver_register

[Greg Kroah-Hartman]

From: Jiasheng Jiang <jiasheng@xxxxxxxxxxx>

[ Upstream commit ab2d2a982ff721f4b029282d9a40602ea46a745e ]

As platform_driver_register() could fail, it should be better
to deal with the return value in order to maintain the code
consisitency.

Fixes: 1ab1f239bf17 ("Bluetooth: hci_intel: Add support for platform driver")
