nfc: constify several pointers to u8, char and sk_buff
[ Upstream commit 3df40eb3a2ea58bf404a38f15a7a2768e4762cb0 ]
Several functions receive pointers to u8, char or sk_buff but do not
modify the contents so make them const. This allows doing the same for
local variables and in total makes the code a little bit safer.
