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)
