crypto: msm: fix Off-by-one error in computation of length for strlcpy()

size + strlen("qcom-") is equal to the length of string not including the
null character. However, we are comparing it to the length of the buffer,
so we need to include the null character, and make a change to make sure
(size + strlen("qcom-")) is smaller than CRYPTO_MAX_ALG_NAME.
