Luís Henriques 1fb3f1bbfd ext4: fix memory leaks in ext4_fname_{setup_filename,prepare_lookup} 
commit 7ca4b085f430f3774c3838b3da569ceccd6a0177 upstream.

If the filename casefolding fails, we'll be leaking memory from the
fscrypt_name struct, namely from the 'crypto_buf.name' member.

Make sure we free it in the error path on both ext4_fname_setup_filename()
and ext4_fname_prepare_lookup() functions.
