Correct several infinite loops/hangs found during fuzzing. The issues fixed here could occur if certain specific malformed NTFS file systems were presented to GRUB. Currently, GRUB does not allow NTFS file system access when lockdown mode is enforced, so these should be of minimal impact. The changes made in this commit generally correct issues such as attempting to iterate through a buffer using a length read from the NTFS file system without confirming the length is larger than 0.
