glsl: free or reuse memory allocated for TF varying
When a shader program is de-serialized the gl_shader_program passed in
may actually still hold memory allocations for the transform feedback
varyings. If that is the case, free the varying names and reallocate
the new storage for the names array.
This fixes a memory leak:
Direct leak of 48 byte(s) in 6 object(s) allocated from:
in malloc (/usr/lib64/gcc/x86_64-pc-linux-gnu/7.3.0/libasan.so+0xdb880)
in transform_feedback_varyings ../../samba/mesa/src/mesa/main/transformfeedback.c:875
in _mesa_TransformFeedbackVaryings ../../samba/mesa/src/mesa/main/transformfeedback.c:985
...
Indirect leak of 42 byte(s) in 6 object(s) allocated from:
in __interceptor_strdup (/usr/lib64/gcc/x86_64-pc-linux-gnu/7.3.0/libasan.so+0x761c8)
in transform_feedback_varyings ../../samba/mesa/src/mesa/main/transformfeedback.c:887
in _mesa_TransformFeedbackVaryings ../../samba/mesa/src/mesa/main/transformfeedback.c:985
