alpha/PCI: Remove WARN from __pci_mmap_fits() and __legacy_mmap_fits()
Remove the WARN() that fires when userspace attempts to mmap beyond the BAR bounds. The check still returns 0 to reject the mapping, but the warning is excessive for normal operation. A similar warning was removed from the PCI core in the commit 3b519e4ea618 ("PCI: fix size checks for mmap() on /proc/bus/pci files").
