[lvc-project] [PATCH] gfs2: eliminate unreachable code in gfs2_freeze_super()

[Alexey Velichayshiy]

The general error check after gfs2_do_thaw() made the subsequent
specific error handlers for -EBUSY and -EIO unreachable. Remove
the redundant general check to ensure proper error handling
for specific cases while preserving the retry mechanism.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
