crypto - Avoid free() namespace collision
gcc-10 complains about using the name of a standard library function in the kernel, as we are not building with -ffreestanding: crypto/xts.c:325:13: error: conflicting types for built-in function 'free'; expected 'void(void *)' [-Werror=builtin-declaration-mismatch] 325 | static void free(struct skcipher_instance *inst) | ^~~~ crypto/lrw.c:290:13: error: conflicting types for built-in function 'free'; expected 'void(void *)' [-Werror=builtin-declaration-mismatch] 290 | static void free(struct skcipher_instance *inst) | ^~~~ crypto/lrw.c:27:1: note: 'free' is declared in header '<stdlib.h>' The xts and lrw cipher implementations run into this because they do not use the conventional namespaced function names. It might be better to rename all local functions in those files to help with things like 'ctags' and 'grep', but just renaming these two avoids the build issue. I picked the more verbose crypto_xts_free() and crypto_lrw_free() names for consistency with several other drivers that do use namespaced function names.
