Hans de Goede dc8a7e83aa [media] pwc: Remove dead snapshot code
The in kernel version of the pwc driver has never supported snapshot
mode, and now that we no longer support the pixfmt.priv abuse there also
no longer is a way for userspace to request it, rendering all the code in
question dead (never called), so remove it.

/* Linux driver for Philips webcam
(C) 2004-2006 Luc Saillard (luc@saillard.org)
NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx
driver and thus may have bugs that are not present in the original version.
Please send bug reports and support requests to <luc@saillard.org>.
The decompression routines have been implemented by reverse-engineering the
Nemosoft binary pwcx module. Caveat emptor.
