habanalabs: Fix an error handling path in 'hl_pci_probe()'

BugLink: https://bugs.launchpad.net/bugs/1938340
[ 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.
