Michal Kazior e13cf7a313 ath10k: move fw_crash_dump allocation 
The fw_crash_data was allocated too late. Upon
early firmware crash, before registering to
mac80211, it was possible to crash the whole
system:

 ---[ end trace 5d0ed15b050bcc1f ]---
 Kernel panic - not syncing: Fatal exception in interrupt
 Kernel Offset: 0x0 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffff9fffffff)
 ---[ end Kernel panic - not syncing: Fatal exception in interrupt

To prevent that split debug functions and allocate
fw_crash_data earlier.
