crypto: tcrypt - Use pr_cont to print test results 

For some test cases, a line break gets inserted between the test banner
and the results. For example, with mode=211 this is the output:

[...]
      testing speed of rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption
[...] test 0 (160 bit key, 16 byte blocks):
[...] 1 operation in 2373 cycles (16 bytes)

--snip--

[...]
      testing speed of gcm(aes) (generic-gcm-aesni) encryption
[...] test 0 (128 bit key, 16 byte blocks):
[...] 1 operation in 2338 cycles (16 bytes)

Similar behavior is seen in the following cases as well:

  modprobe tcrypt mode=212
  modprobe tcrypt mode=213
  modprobe tcrypt mode=221
  modprobe tcrypt mode=300 sec=1
  modprobe tcrypt mode=400 sec=1

This doesn't happen with mode=215:

[...] tcrypt:
              testing speed of multibuffer rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption
[...] tcrypt: test 0 (160 bit key, 16 byte blocks): 1 operation in 2215 cycles (16 bytes)

--snip--

[...] tcrypt:
              testing speed of multibuffer gcm(aes) (generic-gcm-aesni) encryption
[...] tcrypt: test 0 (128 bit key, 16 byte blocks): 1 operation in 2191 cycles (16 bytes)

This print inconsistency is because printk() is used instead of pr_cont()
in a few places. Change these to be pr_cont().

checkpatch warns that pr_cont() shouldn't be used. This can be ignored in
this context as tcrypt already uses pr_cont().
