Matteo Croce af8e2b68f9 pstore: Fix linking when crypto API disabled
commit fd49e03280e596e54edb93a91bc96170f8e97e4a upstream.

When building a kernel with CONFIG_PSTORE=y and CONFIG_CRYPTO not set,
a build error happens:

    ld: fs/pstore/platform.o: in function `pstore_dump':
    platform.c:(.text+0x3f9): undefined reference to `crypto_comp_compress'
    ld: fs/pstore/platform.o: in function `pstore_get_backend_records':
    platform.c:(.text+0x784): undefined reference to `crypto_comp_decompress'

This because some pstore code uses crypto_comp_(de)compress regardless
of the CONFIG_CRYPTO status. Fix it by wrapping the (de)compress usage
by IS_ENABLED(CONFIG_PSTORE_COMPRESS)
