mwifiex: cancel pcie/sdio work in remove/shutdown handler
The last command used to shutdown firmware might be timeout, and trigger firmware dump in asynchronous pcie/sdio work. The remove/shutdown handler will continue free core data structure private/adapter, which might be dereferenced in pcie/sdio work, finally crash the kernel. Sync and Cancel pcie/sdio work, could be a fix for above cornel case. In this way, the last command timeout could be handled properly.
