Guangshuo Li e784f2ea0b floppy: fix reference leak on platform_device_register() failure 
When platform_device_register() fails in do_floppy_init(), the embedded
struct device in floppy_device[drive] has already been initialized by
device_initialize(), but the failure path jumps to out_remove_drives
without dropping the device reference for the current drive.

Previously registered floppy devices are cleaned up in out_remove_drives,
but the device for the drive that fails registration is not, leading to
a reference leak.

The issue was identified by a static analysis tool I developed and
confirmed by manual review. Fix this by calling put_device() for the
current floppy device before jumping to the common cleanup path.

Fixes: 94fd0db7bf ("[PATCH] Floppy: Add cmos attribute to floppy driver")
