[PATCH] smb/client: use %pe to print error pointer

[Fredric Cover]

From: Fredric Cover <fredric.cover.lkernel@xxxxxxxxx>

Currently, __reconnect_target_locked() prints the error pointer
'hostname' using PTR_ERR() and %ld, printing only the error code.

Fix this by using by using %pe to print the error symbolic code instead,
and remove PTR_ERR().

Found via coccicheck. Tested to compile with CONFIG_CIFS_DFS_UPCALL
to ensure that __reconnect_target_locked is actually compiled.
