Subject: [PATCH AUTOSEL 5.2 93/94] enetc: Add missing call to 'pci_free_irq_vectors()' in probe and remove functions

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

[ Upstream commit dd7078f05e1b774a9e8c9f117101d97e4ccd0691 ]

Call to 'pci_free_irq_vectors()' are missing both in the error handling
path of the probe function, and in the remove function.
Add them.

Fixes: 19971f5ea0ab ("enetc: add PTP clock driver")
