crypto: polyval - Rename conflicting functions

Rename polyval_init() and polyval_update(), in preparation for adding
library functions with the same name to <crypto/polyval.h>.

Note that polyval-generic.c will be removed later, as it will be
superseded by the library.  This commit just keeps the kernel building
for the initial introduction of the library.
