accel/habanalabs: set hl_capture_*_err storage-class-specifier to static

smatch reports
drivers/accel/habanalabs/common/device.c:2619:6: warning:
  symbol 'hl_capture_hw_err' was not declared. Should it be static?
drivers/accel/habanalabs/common/device.c:2641:6: warning:
  symbol 'hl_capture_fw_err' was not declared. Should it be static?

both are only used in device.c, so they should be static
