rGaf00e00f23a1: ufshci: initialize desc_size for non-descriptor query requests

Summary

The flag and attribute query builders left param.desc_size
uninitialized, so stack garbage was sent as the query UPIU length
field. Devices generally ignore the length for these opcodes, which
hid the bug. Zero it explicitly.
