staging: rtl8723bs: Use boolean false instead of integer 0

In the struct definition, adaptivity_flag is defined as type 'bool'.
This change replaces the integer literal 0 with the boolean
constant false to match the declared type. It ensures semantic
correctness, and aligns with kernel coding conventions
that prefer true/false over 1/0 for bool types.
