Subject: PCI/MSI: Fix memory leak in free_msi_irqs()

From: Alexei Starovoitov <ast@xxxxxxxxxxxx>

commit b701c0b1fe819a2083fc6ec5332e0e4492b9516d upstream.

free_msi_irqs() is leaking memory, since list_for_each_entry(entry,
&dev->msi_list, list) {...} is never executed, because dev->msi_list is
made empty by the loop just above this one.

Fix it by relying on zero termination of attribute array like
populate_msi_sysfs() does.

Fixes: 1c51b50c2995 ("PCI/MSI: Export MSI mode using attributes, not kobjects")
