ASoC: tegra: Fix 24bit usecase

Browse Source 
The tegra_dai_fixup function was incorrectly updating the format mask
when S24_LE format was requested and DAI has 32-bit sample width incase
the stream on that DAI is already running.

S24_LE format uses 32-bit physical width on the DAI interface, but
the format mask should remain as S24_LE to maintain proper format
negotiation. The fix adds a check to skip format mask updates when
S24_LE is requested and DAI sample_bits is 32.

This resolves issues with RT5640 and other codecs that support
24-bit audio formats on Tegra platforms.
