[PATCH] ath11k: fix error handling in ath11k_qmi_assign_target_mem_chunk()

[trix at redhat.com]

From: Tom Rix <trix at redhat.com>

Clang static analysis reports this problem
qmi.c:1935:5: warning: Undefined or garbage value returned to caller
  return ret;
  ^~~~~~~~~~

ret is uninitialized.  When of_parse_phandle() fails, garbage is
returned.  So return -EINVAL.

Fixes: 6ac04bdc5edb ("ath11k: Use reserved host DDR addresses from DT for PCI devices")
