[PATCH v2] lib/string_helpers: Use the given gfp flag when allocating memory

[Christophe JAILLET]

kstrdup_quotable_cmdline() and kstrdup_quotable_file() are 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 these functions 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.

v2: Add the change for kstrdup_quotable_file()
