[PATCH 2/3] mkimage: fit: Unmmap the memory before closing fd in fit_import_data()

From: Lihua Zhao Without calling munmap(), the follow-up call to open() the same file with a flag O_TRUNC seems not to cause any issue on Linux, but it fails on Windows with error like below: Can't open kernel_fdt.itb.tmp: Permission denied Fix this by unmapping the memory before closing fd
