platform/x86: mlx-platform: call pci_dev_put() to balance the refcount
[ Upstream commit 185e1b1d91e419445d3fd99c1c0376a970438acf ]
mlxplat_pci_fpga_device_init() calls pci_get_device() but does not
release the refcount on error path. Call pci_dev_put() on the error path
and in mlxplat_pci_fpga_device_exit() to fix this.
This bug was found by an experimental static analysis tool that I am
developing.
