cxl: Test CXL_DECODER_F_LOCK as a bitmask
The CXL decoder flags are defined as bitmasks, not bit indices.
Using test_bit() to check them interprets the mask value as a bit
index, which is the wrong test.
For CXL_DECODER_F_LOCK the test reads beyond the defined bits, causing
the test to always return false and allowing resets that should have
been blocked.
Replace test_bit() with a bitmask check.
