resize! broken

[kose-y]

Describe the bug
resize! falls back to GPUArrays implementation and then fails, with error message "buffer not defined"

To Reproduce
The Minimal Working Example (MWE) for this bug:

using CuArrays
y = cu([1, 3, 5])
resize!(y, 10)

UndefVarError: buffer not defined

Stacktrace:
 [1] resize!(::CuArray{Float32,1}, ::Tuple{Int64}) at /home/kose/.julia/packages/GPUArrays/J4c3Q/src/vectors.jl:8
 [2] resize!(::CuArray{Float32,1}, ::Int64) at /home/kose/.julia/packages/GPUArrays/J4c3Q/src/vectors.jl:4
 [3] top-level scope at In[82]:3

Expected behavior
resize theh vector y to size 10.
