qcacld-3.0: Remove obsolete HAL_SELF_STA_PER_BSS condition
Currently Kbuild unconditionally sets -DHAL_SELF_STA_PER_BSS=1. There
is only one place where this macro is referenced, and it actually
requires that the macro be set for the driver to work. Since this
logic isn't really conditional, remove the conditional compilation.
