lib/idxd: Fixed compilation issue (gcc 12.2.1)

Browse Source 
Added initialization of	the prev_crc variable to avoid compilation error:

idxd.c: In function ?spdk_idxd_submit_copy_crc32c?:
idxd.c:1138:51: error: ?prev_crc? may be used uninitialized [-Werror=maybe-uninitialized]
 1138 |                                 desc->crc32c.addr = prev_crc;
      |                                 ~~~~~~~~~~~~~~~~~~^~~~~~~~~~
idxd.c:1081:18: note: ?prev_crc? was declared here
 1081 |         uint64_t prev_crc;
      |                  ^~~~~~~~
