Yi Liu f476dffc52 vfio/pci: Init the count variable in collecting hot-reset devices 
[ Upstream commit 5a88a3f67e ]

The count variable is used without initialization, it results in mistakes
in the device counting and crashes the userspace if the get hot reset info
path is triggered.

Fixes: f6944d4a0b ("vfio/pci: Collect hot-reset devices to local buffer")
