Zheyu Ma 222292930c media: cx25821: Fix the warning when removing the module

[ Upstream commit 2203436a4d24302871617373a7eb21bc17e38762 ]

When removing the module, we will get the following warning:

[   14.746697] remove_proc_entry: removing non-empty directory 'irq/21', leaking at least 'cx25821[1]'
[   14.747449] WARNING: CPU: 4 PID: 368 at fs/proc/generic.c:717 remove_proc_entry+0x389/0x3f0

Fix this by freeing the irq before call pci_disable_device().
