MIPS/GAS: Remove stale `prev_reloc_op_frag' variable

Ever since commit 4d7206a284ee ("Rework MIPS macro relaxation, fix string
merging bug"), <https://sourceware.org/ml/binutils/2004-01/msg00248.html>,
`prev_reloc_op_frag' has only been set and never used.  Remove it then.

	gas/
	* config/tc-mips.c (prev_reloc_op_frag): Remove variable.
	(my_getSmallExpression): Adjust accordingly.
