[PATCH] cxl/core: fix test_bit misuse with CXL_DECODER_F_ bitmask flags

[Gregory Price]

CXL_DECODER_F_LOCK (BIT(4) = 16) and CXL_DECODER_F_NORMALIZED_ADDRESSING
(BIT(6) = 64) are bit masks, but three call sites pass them to test_bit()
which expects a bit number.

Replace test_bit() with direct bitmask tests, consistent with every other
use of these flags.

Fixes: 2230c4bdc412 ("cxl: Add handling of locked CXL decoder")
