[PATCH 2/3] lib/crc/crc32: change crc32() from macro to inline function and remove cast

[Eric Biggers <ebiggers@kernel.org>]

From: Eric Biggers <ebiggers@google.com>

There's no need for crc32() to be a macro.  Make it an inline function
instead.  Also, remove the cast of the data pointer to
'unsigned char const *', which is no longer necessary now that the type
used in the function prototype is 'const void *'.
