usb: gadget: f_mass_storage: Fix memory leak of fsg buffers
In fsg_common_init, we allocate some buffers via memalign().
However, these buffers are never freed.
Because of that, we cannot call => ums command multiple times on boards
with low memory (CONFIG_SYS_MALLOC_LEN=0x81000):
=> ums 0 mmc 2
UMS: LUN 0, dev mmc 2, hwpart 0, sector 0x0, count 0x3a3e000
|crq->brequest:0x0
CTRL+C - Operation aborted
=> ums 0 mmc 2
UMS: LUN 0, dev mmc 2, hwpart 0, sector 0x0, count 0x3a3e000
failed to start <NULL>: -12
g_dnl_register: failed!, error: -12
g_dnl_register failed
Make sure the fsg buffers are freed when the gadget is unbound by
calling fsg_common_release() in fsg_unbind().
