Sebastian Ott 19f7767e29 misc/genwqe: get rid of atomic allocations

we received reports of failed allocations in genwqe code:

[  733.551082] no locks held by genwqe_gzip/1846.

This specific allocation and some others in genwqe are unnecessary flagged
as atomic.

All of genwqe's atomic allocations happen in a context where it's allowed
to sleep. Change these to use GFP_KERNEL.
