[PATCH] crypto: tcrypt - removed unused variable.

[Vakul Garg <vakul@xxxxxxxxxxxxx>]

Removed unused variable for storing output string from:

	(a) test_ahash_jiffies_digest()
	(b) test_ahash_jiffies()
	(c) test_ahash_cycles_digest()
	(d) test_ahash_cycles()

This variable is not needed in above functions since the caller function
test_ahash_speed() already sets output buffer in the ahash transform using
ahash_request_set_crypt().
