This change helps to run script on machines with quite long uptime.
Without this the following error emerges:
File: ./dat_14M.img
umount: /mnt/tmp-ums-test: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
TX: md5sum:083d3d22b542d3ecba61b12d17e03f9f
mount: /dev/sdd6 already mounted or /mnt/tmp-ums-test busy
mount: according to mtab, /dev/sdd6 is already mounted on /mnt/tmp-ums-test

UMS test script.
ums_gadget_test.sh
==================
Example usage:
1. On the target:
create UMS exportable partitions (with e.g. gpt write), or specify a
partition number (PART_NUM) as "-" to use the entire device
ums 0 mmc 0
2. On the host:
sudo test/ums/ums_gadget_test.sh VID PID PART_NUM [-f FILE_SYSTEM] [test_file]
e.g. sudo test/ums/ums_gadget_test.sh 0525 a4a5 6 -f vfat ./dat_14M.img
... where:
VID - UMS device USB Vendor ID
PID - UMS device USB Product ID
PART_NUM - is the partition number on which UMS operates or "-" to use the
whole device
Information about available partitions on the target one can read with using
the 'mmc part' or 'part list' commands.
The partition num (PART_NUM) can be specified as '-' for using the whole device.
The [-f FILE_SYSTEM] optional switch allows for formatting target partition to
FILE_SYSTEM.
The last, optional [test_file] parameter is for specifying the exact test file
to use.
