crypto, xor: Sanitize checksumming function selection output

crypto, xor: Sanitize checksumming function selection output

Currently, it says

[    1.015541] xor: automatically using best checksumming function: generic_sse
[    1.040769]    generic_sse:  6679.000 MB/sec
[    1.045377] xor: using function: generic_sse (6679.000 MB/sec)

and repeats the function name three times unnecessarily. Change it into

[    1.015115] xor: automatically using best checksumming function:
[    1.040794]    generic_sse:  6680.000 MB/sec

and save us a line in dmesg.

No functional change.
