disp: msm: sde: remove WB output buffer pitch alignment check

Currently, driver enforces the allocated WB output buffer to be 256 bits
aligned in memory in order to optimize DDR access and meet maximum system
bandwidth requirements.

Since there are no functional failures with using a 256 bits unaligned
buffer, this change removes this unnecessary check.
