Subject: [PATCH v2 2/4] crypto: tcrypt - Use pr_info/pr_err

Currently, there's mixed use of printk() and pr_info()/pr_err(). The latter
prints the module name (because pr_fmt() is defined so) but the former does
not. As a result there's inconsistency in the printed output. For example:

modprobe mode=211:

[...] test 0 (160 bit key, 16 byte blocks): 1 operation in 2320 cycles (16 bytes)
[...] test 1 (160 bit key, 64 byte blocks): 1 operation in 2336 cycles (64 bytes)

modprobe mode=215:

[...] tcrypt: test 0 (160 bit key, 16 byte blocks): 1 operation in 2173 cycles (16 bytes)
[...] tcrypt: test 1 (160 bit key, 64 byte blocks): 1 operation in 2241 cycles (64 bytes)

Replace all instances of printk() with pr_info()/pr_err() so that the
module name is printed consistently.
