[PATCH] reiserfs: reset errval after initializing bitmap cache

Browse Source 
Callers after reiserfs_init_bitmap_cache() expect errval to contain -EINVAL
until much later.  If a condition fails before errval is reset later,
reiserfs_fill_super() will mistakenly return 0, causing an Oops in
do_add_mount().  This patch resets errval to -EINVAL after the call.

I view this as a temporary fix and real error codes should be used
throughout reiserfs_fill_super().
