PCI/MSI: Destroy sysfs before freeing entries
commit 3735459037114d31e5acd9894fad9aed104231a0 upstream.
free_msi_irqs() frees the MSI entries before destroying the sysfs entries
which are exposing them. Nothing prevents a concurrent free while a sysfs
file is read and accesses the possibly freed entry.
Move the sysfs release ahead of freeing the entries.
Fixes: 1c51b50c2995 ("PCI/MSI: Export MSI mode using attributes, not kobjects")
