kstrdup_quotable_cmdline() is given a gfp flag that is passed and used for
memory allocation in kstrdup_quotable() just a few lines below.
It looks reasonable to use this gfp value for the buffer allocated and
freed in kstrdup_quotable_cmdline() as well.

According to what I've found in 5.16, all callers use GFP_KERNEL, so this
patch should be a no-op.
But who knows how it will be used in the future. Better safe than sorry.
