Remove the functions and variables from rtw_security.c that are no more
necessary since the patch (1/2) that replaces getcrc32() with
crc32_le().

v2 --> v3:
Join two related patches in a series because they must be applied in
order (first 1/2, then 2/2). Rebase to the current Greg K-H's tree and resend.

v1 -> v2:
Update the commit message with the URL of v2 of the above-mentioned
patch.
