accel/amdxdna: Fix out-of-bounds memset in command slot handling
The remaining space in a command slot may be smaller than the size of
the command header. Clearing the command header with memset() before
verifying the available slot space can result in an out-of-bounds write
and memory corruption.
Fix this by moving the memset() call after the size validation.
