Peter Maydell 8809baf4e4 target/mips: Handle lock_user() failure in UHI_plog semihosting call 
Coverity notes that we forgot to check the error return from
lock_user() in one place in the handling of the UHI_plog semihosting
call.  Add the missing error handling.

report_fault() is rather brutal in that it will call abort(), but
this is the same error-handling used in the rest of this file.

Resolves: Coverity CID 1490684
Fixes: ea4210600db3c5 ("target/mips: Avoid qemu_semihosting_log_out for UHI_plog")
