ima: Fix potential memory leak in ima_init_crypto()
[ Upstream commit067d252187
] On failure to allocate the SHA1 tfm, IMA fails to initialize and exits without freeing the ima_algo_array. Add the missing kfree() for ima_algo_array to avoid the potential memory leak. Signed-off-by: Jianglei Nie <niejianglei2021@163.com> Fixes:6d94809af6
