block: floppy: Fix uninitialized use of outparam
Fix Smatch-detected error:
drivers/block/floppy.c:3569 fd_locked_ioctl() error:
uninitialized symbol 'outparam'.
Smatch may incorrectly warn about uninitialized use of 'outparam'
in fd_locked_ioctl(), even though all _IOC_READ commands guarantee
its initialization. Initialize outparam to NULL to make this explicit
and suppress the false positive.
