The client is throwing below stacktrace while asan is enabled. The client is facing an issue while application is trying to call removexattr in 2x1 subvol and non-mds subvol is down. As we can see in below stacktrace dht_setxattr_mds_cbk is calling dht_setxattr_non_mds_cbk and dht_setxattr_non_mds_cbk is trying to wipe local because call_cnt is 0 but dht_setxattr_mds_cbk is trying to access frame->local that;s why it is crashed.
x621000051c34 is located 1844 bytes inside of 4164-byte region [0x621000051500,0x621000052544) freed by thread T7 here:
Solution: Use switch instead of using if statement to wind a operation, in case of switch
the code will not try to access local after wind a operation for last dht subvol.
Fixes: #3732
