libc/baselibc: Fix floating point argument access
When commint "Add va_list pointer compiling error workaround"
was introduced path for FLOAT_USER was not updated as all other
places that use va.
It result in va and va_to_pass used if formating string contains
%f and other like "%f %s %s"
This can result in wrong argument selection.
