MIPS LDSO: pass sym_ref parameter to _dl_find_hash() to support PROTECTED symbols
_dl_find_hash() relies on sym_ref parameter to check if the looked-up symbol
is protected. The code fixes a case when _dl_perform_mips_global_got_relocations()
was calling _dl_find_hash() without providing sym_ref parameter.
The bug was causing hangs if a library exporting non-protected symbol was earlier in
link order than library with the same symbol declared as protected.
