[PATCH AUTOSEL 5.4 051/266] m68k/PCI: Fix a memory leak in an error handling path

[Sasha Levin]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit c3f4ec050f56eeab7c1f290321f9b762c95bd332 ]

If 'ioremap' fails, we must free 'bridge', as done in other error handling
path bellow.

Fixes: 19cc4c843f40 ("m68k/PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping hooks")
