media: Replace file->private_data access with file_to_v4l2_fh()
Accessing file->private_data manually to retrieve the v4l2_fh pointer is
error-prone, as the field is a void * and will happily cast implicitly
to any pointer type.
Replace all remaining locations that read the v4l2_fh pointer directly
from file->private_data with usage of the file_to_v4l2_fh() function.
The change was generated manually.
No functional change is intended, this only paves the way to remove
direct accesses to file->private_data and make V4L2 drivers safer.
Other accesses to the field will be addressed separately.
