Thiago Jung Bauermann 556d971bda ima: Fix use after free in ima_read_modsig() 
If we can't parse the PKCS7 in the appended modsig, we will free the modsig
structure and then access one of its members to determine the error value.

Fixes: 39b0709636 ("ima: Implement support for module-style appended signatures")
