ima: remove unnecessary call to ima_must_measure
The original ima_must_measure() function based its results on cached iint information, which required an iint be allocated for all files. Currently, an iint is allocated only for files in policy. As a result, for those files in policy, ima_must_measure() is now called twice: once to determine if the inode is in the measurement policy and, the second time, to determine if it needs to be measured/re-measured. The second call to ima_must_measure() unnecessarily checks to see if the file is in policy. As we already know the file is in policy, this patch removes the second unnecessary call to ima_must_measure(), removes the vestige iint parameter, and just checks the iint directly to determine if the inode has been measured or needs to be measured/re-measured.
