[PATCH] i4l: memory leak fix for sc_ioctl().

Fix leak of `rcvmsg' in sc_ioctl().

There are two returns in the switch in sc_ioctl (the SCIOCSTART case) that
may leak `rcvmsg'.  This patch fixes that by adding a kfree() call at the
beginning of that case.

Bug found by the coverity checker as #1098

Eric Sesterhenn send me a patch to fix the leak(s) by adding 2 kfree()
calls before the returns, I changed that into just a single call at the
beginning.
