[PATCH] Staging: rtl8188eu: core: rtw_security: tidy up crc32_init()

[Merwin Trever Ferrao]

This code generates checkpatch warning:

WARNING: else is not generally useful after a break or return

Moving the declaration to the top of the function we can pull the
code back one tab and it makes it more readable.
