wifi: ath10k: sdio: add missing lock protection in ath10k_sdio_fw_crashed_dump()
ath10k_sdio_fw_crashed_dump() calls ath10k_coredump_new() which requires ar->dump_mutex to be held, as indicated by lockdep_assert_held() in that function. However, the SDIO implementation does not acquire this lock, unlike the PCI and SNOC implementations which properly hold the mutex. Additionally, ar->stats.fw_crash_counter is documented as protected by ar->data_lock in core.h, but the SDIO implementation modifies it without holding this spinlock. Add the missing mutex_lock()/mutex_unlock() around the coredump operations, and add spin_lock_bh()/spin_unlock_bh() around the fw_crash_counter increment, following the pattern used in ath10k_pci_fw_dump_work() and ath10k_snoc_fw_crashed_dump().
