iwlwifi: mvm: fix memory leak in paging
commit 7fdf9663261cc77a516396fec82cee8a8ea07e76 upstream. Currently paging download buffer is freed during the the unloading of the opmode which happens when the driver is unloaded. This causes a memory leak since the paging download buffer is allocated every time we enable the interface, so the download buffer can be allocated many times, but only be freed once. Free paging download buffer during disabling of the interface.
