usb: gadget: f_mass_storage: Fix NULL dereference in fsg_add()
fsg_common_init() can fail when memory is low. In that case, it returns
PTR_ERR().
fsg_add() does not check for failure, and thus dereferences an invalid
fsg_common later, which crashes.
Verify if we receive an error from fsg_common_init() and handle it
gracefully.
