Thorsten Blum c77b33b585 crypto: iaa - Fix out-of-bounds index in find_empty_iaa_compression_mode 
commit 4832930196 upstream.

The local variable 'i' is initialized with -EINVAL, but the for loop
immediately overwrites it and -EINVAL is never returned.

If no empty compression mode can be found, the function would return the
out-of-bounds index IAA_COMP_MODES_MAX, which would cause an invalid
array access in add_iaa_compression_mode().

Fix both issues by returning either a valid index or -EINVAL.
