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.
