crypto: sig - Rename crypto_sig_maxsize() to crypto_sig_keysize()
crypto_sig_maxsize() is a bit of a misnomer as it doesn't return the
maximum signature size, but rather the key size.
Rename it as well as all implementations of the ->max_size callback.
A subsequent commit introduces a crypto_sig_maxsize() function which
returns the actual maximum signature size.
While at it, change the return type of crypto_sig_keysize() from int to
unsigned int for consistency with crypto_akcipher_maxsize(). None of
the callers checks for a negative return value and an error condition
can always be indicated by returning zero.
