Subject: [PATCH 5.12 634/700] habanalabs: Fix an error handling path in hl_pci_probe()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 3002f467a0b0a70aec01d9f446da4ac8c6fda10b ]

If an error occurs after a 'pci_enable_pcie_error_reporting()' call, it
must be undone by a corresponding 'pci_disable_pcie_error_reporting()'
call, as already done in the remove function.

Fixes: 2e5eda4681f9 ("habanalabs: PCIe Advanced Error Reporting support")
