Summary
ima: Fix memory leak in __ima_inode_hash()
Details

In the Linux kernel, the following vulnerability has been resolved:

ima: Fix memory leak in _imainode_hash()

Commit f3cc6b25dcc5 ("ima: always measure and audit files in policy") lets measurement or audit happen even if the file digest cannot be calculated.

As a result, iint->imahash could have been allocated despite imacollect_measurement() returning an error.

Since imahash belongs to a temporary inode metadata structure, declared at the beginning of _imainodehash(), just add a kfree() call if imacollectmeasurement() returns an error different from -ENOMEM (in that case, ima_hash should not have been allocated).
