Subject: [PATCH] habanalabs: Fix an error handling path in 'hl_pci_probe()'

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")
